Canonical Non-Identity Statement

WDC-03 已建立:

World PriorityWorld TruthWorld Moral Worth.\boxed{ \text{World Priority} \neq \text{World Truth} \neq \text{World Moral Worth}. }

並將 Governor 定義為:

computation over worlds\boxed{ \text{computation over worlds} }

的有限資源管理器。

WDC-05 再建立:

World CountIndependent Evidence CountTruth.\boxed{ \text{World Count} \neq \text{Independent Evidence Count} \neq \text{Truth}. }

本文進一步建立:

Worth ComputingWorth BelievingWorth Deploying.\boxed{ \text{Worth Computing} \neq \text{Worth Believing} \neq \text{Worth Deploying}. }

以及:

Best Current WorldBest Next Computation.\boxed{ \text{Best Current World} \neq \text{Best Next Computation}. }

本文不主張:

  • 某個 world 本體上「值得存在」或「不值得存在」;
  • highest-posterior world 一定應取得最多算力;
  • highest-information-gain computation 一定改善實際決策;
  • expected information gain 等於 value of computation;
  • value of computation 存在單一 universal scalar;
  • cheap low-fidelity world 一定值得先算;
  • high-fidelity world 一定比 symbolic / coarse world 更有價值;
  • counterworld 永遠比 support world 重要;
  • exploration、verification、transport、tail-risk 有固定最佳比例;
  • world portfolio optimization 已等同通用科學方法;
  • 本文的 world portfolio 可直接取代 Bayesian experimental design、bandits、MCTS 或 multi-fidelity optimization;
  • 本文已解決所有長期 world-governance normative questions。

摘要

WDC-03 建立 World-Domain Governor,提供:

  • Admit;
  • Schedule;
  • Allocate;
  • Pause;
  • Resume;
  • Preempt;
  • Kill;
  • Archive;
  • Promote。

但 WDC-03 刻意沒有封頂一個更深的問題:

下一單位 computation 究竟應該投到哪個 world?

WDC-05 又進一步指出,多跑一個與現有 worlds 高度相依的 world,可能幾乎沒有增加 independent evidence;相反地,一個低成功率、但能測試 hidden assumption 的 counterworld,可能具有更高證據價值。

因此本文主張:

真正應被 Governor 比較的,不是「哪個 world 比較好」,而是「下一個 world-computation action 的邊際價值」。

本文定義 world-computation action:

cj=(Targetj,Opj,Δbj,j,Hj,qj,κj).\boxed{ c_j = ( Target_j, Op_j, \Delta\mathbf b_j, \ell_j, H_j, q_j, \kappa_j ). }

其中:

  • TargetjTarget_j:world、world family、claim、unknown region 或 external target;
  • OpjOp_j:要執行的 computation operation;
  • Δbj\Delta\mathbf b_j:追加 budget;
  • j\ell_j:fidelity / resolution level;
  • HjH_j:run horizon / deadline;
  • qjq_j:此 computation 服務的 claim / decision;
  • κj\kappa_j:computation contract。

OpjOp_j 至少可以包括:

RunMore,Replicate,ForkCounter,ExploreUnknown,CrossBackend,RefineFidelity,StressTail,Calibrate,TransportTest,ExternalTestProposal.\boxed{ \begin{aligned} &RunMore,\\ &Replicate,\\ &ForkCounter,\\ &ExploreUnknown,\\ &CrossBackend,\\ &RefineFidelity,\\ &StressTail,\\ &Calibrate,\\ &TransportTest,\\ &ExternalTestProposal. \end{aligned} }

因此:

computing a world\boxed{ \text{computing a world} }

不只等於:

再讓某個 world 多跑幾步。

它也可以是:

建立一個完全不同 backend 的獨立 world。

或:

專門建立最強 counterexample branch。

或:

不再增加 simulation,而把 budget 投向 real-data calibration。

本文定義當前 evidence / decision state:

Et=(Et,DW,EW,UW,DT,Atdecision,TD).\boxed{ \mathfrak E_t = ( \mathcal E_t, \mathbf D_W, \mathbf E_W, U_W, D_T, A_t^{decision}, T_D ). }

其中:

  • Et\mathcal E_t:目前 cross-world evidence graph;
  • DW\mathbf D_W:world dependence structure;
  • EW\mathbf E_W:cross-world evidence profiles;
  • UWU_W:unknown / omitted world-family region;
  • DTD_T:world-to-target transport debt;
  • AtdecisionA_t^{decision}:待做的 real decision set;
  • TDT_D:decision deadline。

本文再建立 computation-value vector:

Vt(c)=(VD,VI,VV,VC,VX,VT,VR,VO,C,L,S)c.\boxed{ \mathbf V_t(c) = ( V_D, V_I, V_V, V_C, V_X, V_T, V_R, V_O, -C, -L, -S )_c. }

其中:

  • VDV_D:decision-improvement value;
  • VIV_I:information gain;
  • VVV_V:verification value;
  • VCV_C:counterexample / falsification value;
  • VXV_X:independence / diversity gain;
  • VTV_T:transport-debt reduction;
  • VRV_R:tail-risk / failure-region value;
  • VOV_O:option value / future-computation enabling value;
  • CC:compute / human / verification cost;
  • LL:latency;
  • SS:safety / containment burden。

本文拒絕預設:

Vt(c)one universal scalar.\boxed{ \mathbf V_t(c) \rightarrow \text{one universal scalar}. }

但在明示 task utility:

ωt\omega_t

後,可以局部使用:

Vtproj(c)=ωtVt(c).\boxed{ V_t^{proj}(c) = \omega_t^\top \mathbf V_t(c). }

權重必須:

  • task-relative;
  • versioned;
  • auditable;
  • 不得事後偷偷改到支持已選 computation。

本文接著把 Decision Value of Computation 寫成:

VOCD(c)=EYc[maxaEU(aEt,Yc)]maxaEU(aEt).\boxed{ VOC_D(c) = \mathbb E_{Y_c} \left[ \max_{a} EU( a \mid \mathcal E_t,Y_c ) \right] - \max_a EU( a \mid \mathcal E_t ). }

若 computation cost 可與 decision utility 同尺度比較,則:

NVOCD(c)=VOCD(c)C(c).\boxed{ NVOC_D(c) = VOC_D(c) - C(c). }

但本文同時強調:

VOCDEIG.\boxed{ VOC_D \neq EIG. }

Expected Information Gain 可以寫成:

EIG(c)=I(Θ;YcEt).\boxed{ EIG(c) = I( \Theta; Y_c \mid \mathcal E_t ). }

一個 computation 可以帶來大量 information,卻完全不改變當前 decision;反過來,一個只消除 decision boundary 附近少量 uncertainty 的 world,information gain 不大,卻可能直接改變 action。

因此:

Information ValueDecision Value.\boxed{ \text{Information Value} \neq \text{Decision Value}. }

外部 Bayesian optimal experimental design 正是有限實驗資源下以 expected information gain 選擇實驗的成熟框架;Foster 等人的 variational BOED 工作專門處理 EIG estimation 的昂貴性,而 Zheng 等人的 sequential BOED 進一步直接研究 variable experiment / computation costs 下如何自適應分配額外 computation。這些工作與 WDC 結構相鄰,但不表示 WDC 必須以 mutual information 作唯一 utility。

本文亦建立 Transport Value

VT(c)=E[DT(qEt)DT(qEt,Yc)].\boxed{ V_T(c) = \mathbb E \left[ D_T(q\mid\mathcal E_t) - D_T( q \mid \mathcal E_t,Y_c ) \right]. }

若目前最大的問題不是:

worlds 不夠多,

而是:

simulation 與 reality 的 bridge 太弱,

那麼新的 simulation world 可能:

VT0.V_T\approx0.

此時最值得的 computation 可能是:

  • historical backtest;
  • real-data calibration;
  • hardware experiment;
  • shadow deployment;
  • external measurement。

因此:

More World Compute⇏More Target Evidence.\boxed{ \text{More World Compute} \not\Rightarrow \text{More Target Evidence}. }

本文再建立 Independence Value

VX(c)=ΔIndependence(EtEtYc).\boxed{ V_X(c) = \Delta \operatorname{Independence} ( \mathcal E_t \rightarrow \mathcal E_t\cup Y_c ). }

一個新的 independent backend 即使 prediction 與現有 worlds 一樣,也可能具有高 VXV_X,因為它降低:

所有 agreement 都來自同一 shared bug

的可能性。

相反地,第 1000 個同 backend seed:

VX0V_X\approx0

但可能仍有 stochastic-precision value。

本文建立 Counterexample Value

VC(c)=E[Utility(discover valid failure / counterexample)].\boxed{ V_C(c) = \mathbb E \left[ Utility( \text{discover valid failure / counterexample} ) \right]. }

對 universal / safety claims, VCV_C 可以非常高;對普通 probabilistic frequency estimate,單一 counterexample 的邏輯作用則不同。

因此 computation value 必須知道:

Type(q).\boxed{ Type(q). }

本文進一步提出 Epistemic Deficit Vector

Δt(q)=(δrun,δind,δcounter,δtransport,δfidelity,δtail,δunknown,δdecision).\boxed{ \Delta_t(q) = ( \delta_{run}, \delta_{ind}, \delta_{counter}, \delta_{transport}, \delta_{fidelity}, \delta_{tail}, \delta_{unknown}, \delta_{decision} ). }

其中:

  • δrun\delta_{run}:within-world stochastic / numerical uncertainty;
  • δind\delta_{ind}:independent evidence family deficit;
  • δcounter\delta_{counter}:counterexample-search deficit;
  • δtransport\delta_{transport}:world-to-target transport deficit;
  • δfidelity\delta_{fidelity}:resolution / model-detail deficit;
  • δtail\delta_{tail}:rare-event / risk coverage deficit;
  • δunknown\delta_{unknown}:omitted-world-family / ontology deficit;
  • δdecision\delta_{decision}:decision-critical unresolved uncertainty。

這讓 Governor 不再只是問:

哪個 world 分數最高?

而可以先問:

我們現在真正缺哪一種證據?

若:

δrun0,\delta_{run}\gg0,

優先:

Replicate/RunMore.\boxed{ Replicate / RunMore. }

若:

δind0,\delta_{ind}\gg0,

優先:

CrossBackend/IndependentEvaluator.\boxed{ CrossBackend / IndependentEvaluator. }

若:

δcounter0,\delta_{counter}\gg0,

優先:

ForkCounter/AdversarialWorld.\boxed{ ForkCounter / AdversarialWorld. }

若:

δtransport0,\delta_{transport}\gg0,

優先:

Calibrate/ExternalTest.\boxed{ Calibrate / ExternalTest. }

若:

δtail0,\delta_{tail}\gg0,

優先:

StressTail.\boxed{ StressTail. }

若:

δunknown0,\delta_{unknown}\gg0,

優先:

ExploreUnknown/GenerateNewWorldFamily.\boxed{ ExploreUnknown / GenerateNewWorldFamily. }

這是本文最重要的策略轉換:

World SelectionDeficit-Directed Computation.\boxed{ \text{World Selection} \rightarrow \text{Deficit-Directed Computation}. }

本文進一步建立:

World Computation Portfolio

世界計算投資組合

定義:

ΠtW={(c1,b1),,(cm,bm)}.\boxed{ \Pi_t^W = \{ (c_1,b_1), \dots, (c_m,b_m) \}. }

其中:

bib_i

是 allocation。

要求:

ibiBtG.\boxed{ \sum_i \mathbf b_i \preceq \mathbf B_t^G. }

Portfolio 可以至少包含:

  1. support / refinement computations;
  2. counterworld computations;
  3. independent-backend computations;
  4. stochastic replication;
  5. transport / calibration;
  6. rare-event stress worlds;
  7. unknown-region exploration;
  8. fidelity escalation。

本文拒絕:

ΠtW={全部最高分 worlds}.\boxed{ \Pi_t^W = \{\text{全部最高分 worlds}\}. }

因為這容易造成 WDC-03 的:

World-Mode Collapse

本文提出:

portfolio quality\boxed{ \text{portfolio quality} }

應同時考慮:

  • expected utility;
  • evidence diversity;
  • counterexample coverage;
  • dependence;
  • transport;
  • latency;
  • safety;
  • compute cost。

本文進一步引入 Myopic vs Dynamic Computation Value

Myopic value:

Vmyopic(c)\boxed{ V^{myopic}(c) }

只看 computation cc 完成後立即增加多少 value。

但一個 cheap computation 可能本身價值不大,卻能決定:

是否值得啟動一個極昂貴 high-fidelity world。

因此 dynamic value 需要考慮:

cfuture computation policy.\boxed{ c \rightarrow \text{future computation policy}. }

本文將概念性 dynamic value 寫成:

Vdyn(c)=E[U(ΠfutureYc)]U(ΠfutureEt).\boxed{ V^{dyn}(c) = \mathbb E \left[ U( \Pi_{future}^{\star} \mid Y_c ) \right] - U( \Pi_{future}^{\star} \mid \mathcal E_t ). }

這與 Sezener 與 Dayan 在 MCTS 中區分 static / dynamic values of computation 的問題高度相鄰:一次 simulation 的價值不只可能影響現在 action,也可能影響之後還會做哪些 computations。

因此:

cheap screening computation\boxed{ \text{cheap screening computation} }

可以具有高:

VO\boxed{ V_O }

即 option / computation-enabling value。

本文將這種 dependency 明確表示為 Computation Graph

GCW=(VC,EC).\boxed{ G_C^W = ( V_C, E_C ). }

node:

cic_i

是 possible computations;

edge:

cicjc_i\rightarrow c_j

表示:

做完 cic_i 後,才知道是否值得/是否允許執行 cjc_j

例如:

CoarseWorldHighFidelityWorldExternalTest.\boxed{ CoarseWorld \rightarrow HighFidelityWorld \rightarrow ExternalTest. }

因此 WDC portfolio 不是一個 flat ranking list。

它可以是:

adaptive computation program.\boxed{ \text{adaptive computation program}. }

外部 Hyperband 正是 adaptive resource allocation / early stopping 的重要工程類比:先對大量 configurations 配少量資源,再把更多資源投入較有希望者。本文接受其 coarse-to-fine resource idea,但不接受把「performance winner」直接當 WDC promotion criterion。

WDC 的 cheap world 即使顯示:

hypothesis 失敗,

也可能因為它是一個高價值 counterexample 而被 Promote

所以:

promotionpositive outcome promotion.\boxed{ \text{promotion} \neq \text{positive outcome promotion}. }

本文將 WDC 的多 fidelity 升級機制命名為:

Successive Evidence Escalation

最小層級:

L0L1L2L3L4.\boxed{ L_0 \rightarrow L_1 \rightarrow L_2 \rightarrow L_3 \rightarrow L_4. }

其中:

  • L0L_0:cheap abstract / symbolic screening;
  • L1L_1:low-fidelity runnable world;
  • L2L_2:medium-fidelity replicated world;
  • L3L_3:high-fidelity / cross-backend world;
  • L4L_4:external calibration / real test candidate。

升級條件不是:

結果好看。

而可以是:

  • decision sensitivity high;
  • counterexample importance high;
  • unresolved disagreement high;
  • transport value high;
  • rare risk high;
  • information gain high。

本文同時加入 Low-Fidelity Reliability Gate

外部 multi-fidelity Bayesian optimization 已清楚顯示:便宜 approximation 可以降低昂貴 evaluation 的需求,但若 low-fidelity source 與 target 關係很差,它甚至可能讓總 optimization cost 更高。Mikkola 等人的 robust MFBO 正是針對 unreliable information sources 提出保護機制。

因此 WDC 定義:

ρtarget\boxed{ \rho_{\ell\rightarrow target} }

表示 fidelity level \ell 對 target evidence 的 calibrated reliability。

若:

ρtarget0,\rho_{\ell\rightarrow target}\approx0,

則 cheap world:

must not gate out high-fidelity worlds by itself.\boxed{ \text{must not gate out high-fidelity worlds by itself}. }

因此:

cheapsafe to trust.\boxed{ \text{cheap} \neq \text{safe to trust}. }

本文提出:

Fidelity Escalation Rule

低 fidelity 可以:

  • screen;
  • prioritize;
  • identify gross failures;

但若其 reliability 未被校準,不應單獨:

  • falsify real-world claim;
  • block critical high-fidelity validation;
  • authorize deployment。

本文再建立 World Computation Opportunity Cost

當 Global Budget:

BG\mathbf B_G

固定,

給:

cic_i

更多 compute,

就代表:

cjc_j

少一些。

因此:

OpportunityCost(ci)=Value(best foregone computation).\boxed{ OpportunityCost(c_i) = Value( \text{best foregone computation} ). }

即使:

V(ci)>0,V(c_i)>0,

也可能:

V(ci)<OpportunityCost(ci).\boxed{ V(c_i) < OpportunityCost(c_i). }

此時不該選它。

本文再加入 Deadline-Adjusted Value

若 decision deadline:

TDT_D

而 computation result time:

Tc,T_c,

則結果來得太晚:

Tc>TDT_c>T_D

可能對當前 decision value近乎:

0.0.

定義概念:

VDdeadline(c)=VD(c)P(TcTD).\boxed{ V_D^{deadline}(c) = V_D(c) \cdot P( T_c\le T_D ). }

或使用 domain-specific soft decay。

因此:

more accurate but too late\boxed{ \text{more accurate but too late} }

可能不如:

coarser but decision-timely.\boxed{ \text{coarser but decision-timely}. }

本文亦建立 Meta-Reasoning Cost

估計:

V(c)V(c)

本身也需要:

  • compute;
  • modeling;
  • bookkeeping;
  • uncertainty estimation。

所以:

Cmeta(c)>0.\boxed{ C_{meta}(c)>0. }

如果:

CmetaC_{meta}

接近或超過 world computation cost,

過度精細的 Governor 反而浪費資源。

因此:

Meta-Boundedness Principle

A metareasoner should not spend more resources deciding what to compute than the decision is worth.

可以概念寫成:

VOC(c)>C(c)+Cmeta(c)\boxed{ VOC(c) > C(c)+C_{meta}(c) }

才值得進一步精算;否則可使用 simpler heuristics。

本文進一步定義 Stopping Condition

對 active computation:

ci,c_i,

若:

MV(ci)<θstop,\boxed{ MV(c_i) < \theta_{stop}, }

且不存在:

  • minimum replication obligation;
  • unresolved safety obligation;
  • rare-event obligation;
  • counterexample obligation;
  • deadline-independent archival need;

則可以停止。

但:

stopclaim settled.\boxed{ \text{stop} \neq \text{claim settled}. }

可能只是:

在目前 budget 下,不值得繼續計算。

本文再定義 Expansion Condition

如果:

SE(q)\boxed{ S_E(q)\uparrow }

即 WDC-05 的 backend / lineage / evaluator sensitivity 高,

則不是繼續跑同 family,

而應:

ExpandFamily.\boxed{ ExpandFamily. }

如果:

DT(q),D_T(q)\uparrow,

則:

ExpandTransportEvidence.\boxed{ ExpandTransportEvidence. }

如果:

UW,U_W\uparrow,

則:

ExpandOntology/WorldFamily.\boxed{ ExpandOntology / WorldFamily. }

因此:

more samplesright response to every uncertainty.\boxed{ \text{more samples} \neq \text{right response to every uncertainty}. }

本文提出 World Portfolio Regret

在 finite benchmark 中,如果 exhaustive computation 可以知道最佳 allocation:

Π,\Pi^\star,

而 Governor 實際使用:

Π,\Pi,

則:

RegretG(B)=U(Π)U(Π).\boxed{ Regret_G(B) = U( \Pi^\star ) - U( \Pi ). }

真實世界通常不知道:

Π,\Pi^\star,

但有限 simulator benchmark 可用此測 Governor。

本文進一步建立 Computation-Value Calibration

對每個 computation:

ci,c_i,

執行前預測:

V^i.\widehat V_i.

執行後測:

Virealized.V_i^{realized}.

保存:

(V^i,Virealized).\boxed{ ( \widehat V_i, V_i^{realized} ). }

長期可檢查:

  • information-gain overestimate;
  • decision-value overestimate;
  • counterexample underestimation;
  • transport-value calibration;
  • latency errors。

因此 Governor 不只 calibration worlds,

也 calibration:

its own computation choices.\boxed{ \text{its own computation choices}. }

本文稱:

Meta-Calibration

若 Governor 永遠認為:

support worlds 很有價值,

但實際 realized gain 長期低,

它必須調整 allocation model。

本文再建立 World Portfolio Modes

Mode S — Support Refinement

精化目前 leading family。

Mode C — Counterexample Search

找 strongest plausible failure。

Mode I — Independence Expansion

不同 backend / data / evaluator。

Mode R — Replication

降低 stochastic / numerical uncertainty。

Mode T — Transport

calibration / external mapping。

Mode H — High-Fidelity Escalation

增加 dynamics / actor / temporal fidelity。

Mode U — Unknown-Region Exploration

建立新 ontology / new world family。

Mode X — Tail / Stress Exploration

低機率、高 impact 或安全失敗區域。

因此:

ΠtW=(BS,BC,BI,BR,BT,BH,BU,BX).\boxed{ \Pi_t^W = ( B_S, B_C, B_I, B_R, B_T, B_H, B_U, B_X ). }

這只是 budget-coordinate representation,不要求:

Bi\sum B_i

永遠以固定比例分配。

本文提出 Adaptive Portfolio Rebalancing

Πt+1W=RP(ΠtW,Δt(q),Outcomet,Deadlinet).\boxed{ \Pi_{t+1}^W = \mathcal R_P( \Pi_t^W, \Delta_t(q), Outcome_t, Deadline_t ). }

如果新 counterexample 出現:

BC,BI,BHB_C, B_I, B_H \uparrow

可能合理。

如果跨 backend 已非常穩,但 transport debt 高:

BT,BS.B_T\uparrow, \qquad B_S\downarrow.

如果 deadline 接近:

BDdecisionsensitive.B_D^{decision-sensitive}\uparrow.

本文再建立 World Portfolio Frontier

FP=ParetoFront(DecisionGain,InfoGain,Verification,CounterCoverage,Independence,Transport,TailCoverage,Cost,Latency).\boxed{ \mathcal F_P = ParetoFront \left( DecisionGain, InfoGain, Verification, CounterCoverage, Independence, Transport, TailCoverage, -Cost, -Latency \right). }

WDC 不要求 portfolio 被壓成:

PortfolioScore=87.4.\boxed{ PortfolioScore=87.4. }

本文同時處理 Rare-World Preservation

假設某 world:

WrW_r

被 current model 認為:

P(Wr)1,P(W_r)\ll1,

但:

Impact(Wr)1.Impact(W_r)\gg1.

若它涉及:

  • catastrophic safety failure;
  • irreversible option loss;
  • systemic collapse;
  • security breach;

則其 computation value 可能高。

因此:

low probabilitylow portfolio value.\boxed{ \text{low probability} \neq \text{low portfolio value}. }

這與 WDC-03 的 diversity reserve 及 WDC-05 的 counterexample preservation 接軌。

本文提出 Tail Computation Reserve

BX\boxed{ B_X }

作為可選 governance component,用於:

  • stress test;
  • rare-event search;
  • worst-case branch;
  • adversarial agent policy。

它不是要求所有系統固定保留某百分比,而是禁止:

因為 leading posterior 很高,就把所有 tail worlds 永久砍光。

本文再建立 Discriminative World Value

有時兩個 hypotheses:

H1,H2H_1,H_2

都能解釋現有 evidence。

最有價值 world 不是:

最可能支持 H1H_1 的 world。

而是:

最能讓 H1H_1H2H_2 產生不同 predictions 的 world。

定義:

Vdisc(c)=E[d(P(YcH1),P(YcH2))].\boxed{ V_{disc}(c) = \mathbb E \left[ d( P(Y_c\mid H_1), P(Y_c\mid H_2) ) \right]. }

或其他 task-specific discriminability metric。

這與 optimal experimental design 的核心精神相鄰:

選擇最能減少 relevant uncertainty 的 experiment。

因此:

best evidence-producing worldmost realistic-looking world.\boxed{ \text{best evidence-producing world} \neq \text{most realistic-looking world}. }

本文再建立 Calibration World

如果 target reality 有 historical cases:

r1,,rm,r_1,\ldots,r_m,

可以專門建立:

Wcal\boxed{ W^{cal} }

用於:

  • fit;
  • validate;
  • transport-debt estimation。

其價值不一定來自產生新 future,而是:

measuring how wrong current worlds are.\boxed{ \text{measuring how wrong current worlds are}. }

因此:

a world that reveals model error\boxed{ \text{a world that reveals model error} }

可以比:

a world that confirms preferred outcome\boxed{ \text{a world that confirms preferred outcome} }

更值得算。

本文再建立 World-Portfolio Dependency Penalty

若 proposed computation:

cc

高度依賴 active portfolio 中同一 family:

Fk,F_k,

則新增 evidence 的 marginal independence value下降。

概念:

VX(c)asDependence(c,ΠtW).\boxed{ V_X(c) \downarrow \quad \text{as} \quad Dependence( c,\Pi_t^W ) \uparrow. }

這直接延續 WDC-05。

本文因此提出:

Correlation-Aware World Allocation

Allocate compute according to the marginal contribution of a world computation to the evidence portfolio, not merely to the standalone quality of its world.

一個 standalone 很強的 world:

WiW_i

如果 portfolio 已有:

2020

個幾乎相同 worlds,

其 marginal value 可能低。

反之,一個 standalone fidelity 稍低但真正獨立的 world:

WjW_j

可能有更高 portfolio value。

本文接著建立 Computation Admission Record

computation_id
target_world_or_claim
operation
requested_budget
fidelity
deadline
expected_decision_value
expected_information_gain
expected_verification_value
expected_counterexample_value
expected_independence_gain
expected_transport_gain
tail_risk_value
estimated_cost
estimated_latency
meta_cost
portfolio_dependence

執行後建立:

computation_id
realized_cost
realized_latency
realized_information_gain
decision_changed
counterexample_found
new_family_created
transport_debt_reduced
world_promoted
world_invalidated
followup_actions

這使 WDC-06 可以真正被實驗。

本文最後提出:

World Computation Value Principle

The object of allocation is not a world's abstract worth but the expected marginal value of a specific next computation on the current evidence and decision state.

Deficit-Directed Computation Principle

World computation should target the dominant epistemic or decision deficit—replication, independence, counterexample, transport, fidelity, tail risk, or unknown-world coverage—rather than reflexively adding more samples to the current leading family.

Portfolio, Not Winner Principle

A mature WDC Governor should maintain a portfolio of complementary computation modes rather than only expanding the current highest-ranked world.

Decision–Information Separation Principle

Expected information gain and expected decision improvement are distinct; a computation may be scientifically informative yet decision-irrelevant, or decision-critical with modest total information gain.

Dynamic Computation Principle

The value of a computation can include the future computations it enables or prevents; therefore world allocation should not be assumed purely myopic.

Fidelity Reliability Principle

Low-fidelity worlds may be used for screening and prioritization only to the degree that their relationship to the target is calibrated; cheap but unreliable worlds can increase rather than decrease total cost.

Meta-Boundedness Principle

Estimating the value of computation is itself a computation and must be bounded by its expected benefit.

下一篇 WDC-07 將研究:

World Ensemble Learning

《世界集合學習:如何讓跨世界結果反過來更新生成器、模型、Governor 與未來空間》

也就是:

我們已經會挑 world、跑 world、比較 world。那這些結果如何真正讓整個 WDC system 變聰明,而不是每輪重新從頭開始?

關鍵詞: Value of Computation、World Portfolio、Metareasoning、Bayesian Experimental Design、Multi-Fidelity Computation、Counterworlds、Transport Debt、World-Domain Governor、WDC


1. WDC-06 的真正 allocation unit 不是 World

Governor 若只對:

WiW_i

打永久分數,

容易產生錯誤。


2. Because the same World may need different next computations

例如:

WiW_i

可以:

  • run more;
  • fork;
  • replicate;
  • upgrade fidelity;
  • change evaluator。

3. Therefore

WorldWorld Computation Action.\boxed{ \text{World} \neq \text{World Computation Action}. }

4. Computation Action

c=(Target,Op,Budget,Fidelity,Horizon,Claim,Contract).\boxed{ c = ( Target, Op, Budget, Fidelity, Horizon, Claim, Contract ). }

5. Target Can Be Existing World

Target=Wi.Target=W_i.

6. Or Missing World Family

Target=UW.Target=U_W.

7. Or Claim

Target=q.Target=q.

8. Or Transport Gap

Target=DT.Target=D_T.

9. Operation Can Create a New World

Op=CrossBackend.Op=CrossBackend.

10. Or No New World

Op=CalibrateExisting.Op=CalibrateExisting.

11. This Is Important

Sometimes best next action is:

stop simulating.\boxed{ \text{stop simulating}. }

12. And Measure Reality


13. Current Evidence State

Et.\boxed{ \mathfrak E_t. }

14. It Includes Cross-World Evidence Graph

Et.\mathcal E_t.

15. Dependence

DW.\mathbf D_W.

16. Unknown World Mass

UW.U_W.

17. Transport Debt

DT.D_T.

18. Decision Set

Atdecision.A_t^{decision}.

19. Deadline

TD.T_D.

20. Computation Changes Evidence State

Etc,YcEt+1.\boxed{ \mathfrak E_t \xrightarrow{c,Y_c} \mathfrak E_{t+1}. }

21. WDC-06 Is a Meta-Level MDP-Like Problem

State:

E.\mathfrak E.

Action:

c.c.

Outcome:

Yc.Y_c.

22. But We Do Not Claim Standard MDP Assumptions Always Hold


23. Metareasoning

The system reasons about:

which reasoning / simulation to do.\boxed{ \text{which reasoning / simulation to do}. }

24. Rational Metareasoning External Calibration

Lieder et al. formulate algorithm selection as rational metareasoning。


25. Core Neighboring Idea

use expected consequences of computations to choose among cognitive strategies。


26. WDC Extension

strategy is not just algorithm。

It can be:

a whole runnable world computation.\boxed{ \text{a whole runnable world computation}. }

27. Decision VOC

VOCD(c).\boxed{ VOC_D(c). }

28. Baseline Decision

a=argmaxaEU(aEt).a^\star = \arg\max_a EU(a\mid\mathcal E_t).

29. After Computation

a(Yc).a^\star(Y_c).

30. Improvement

VOCD=E[EU(a(Yc))]EU(a).\boxed{ VOC_D = E[ EU(a^\star(Y_c)) ] - EU(a^\star). }

31. Cost

Net:

NVOCD=VOCDC.\boxed{ NVOC_D = VOC_D-C. }

32. This Requires Utility Model

If unavailable:

report unprojected vector。


33. Information Value

VI=EIG.\boxed{ V_I=EIG. }

when probabilistic latent target exists。


34. Expected Information Gain

I(Θ;Yc).I(\Theta;Y_c).

35. But EIG Can Be High for Irrelevant Parameter


36. Example

Learn precise parameter that doesn't affect action。


37. Decision Value Near Zero


38. Conversely

one binary test near action threshold。


39. Low entropy reduction

but flips decision。


40. Therefore

EIGVOCD.\boxed{ EIG\neq VOC_D. }

41. BOED External Calibration

Foster et al. call EIG central but computationally difficult。


42. This Meta-Point Matters

Even estimating experiment value can be expensive。


43. Zheng et al. 2020

explicitly allocate computation to refine MI estimates with variable costs。


44. WDC Analogy

We may need to allocate compute:

to estimate which world computation is worth doing。


45. Meta-Compute

Cmeta.C_{meta}.

46. Infinite Meta-Regress Risk

Should we compute the value of computing the value of computing?


47. Stop by bounded metareasoning

DepthmetaDmeta.\boxed{ Depth_{meta}\le D_{meta}. }

48. Or simple heuristic gate


49. Meta-Heuristic

if one candidate obviously dominates in cost/value bounds, act。


50. Only expensive VOC estimation near ambiguity


51. Value Bounds

V(c)V(c)V+(c).\boxed{ V^{-}(c) \le V(c) \le V^{+}(c). }

52. If Upper Bound Below Cost

reject。


53. If Lower Bound Clearly Highest

admit。


54. This Mirrors Sequential Bound Refinement Idea


55. Dynamic VOC

Sezener & Dayan distinguish values accounting for future computations。


56. WDC Example

cheap world says:

possible failure。


57. That unlocks

expensive failure-analysis worlds.\boxed{ \text{expensive failure-analysis worlds}. }

58. So cheap world's total value includes follow-up opportunities


59. Option Value

VO(c).\boxed{ V_O(c). }

60. Negative Option Value Also Possible

Computation may make deadline miss。


61. Computation Dependency Graph

GCW.G_C^W.

62. Node = computation


63. Edge = unlock / condition / block


64. Example

c0:CheapScreen.c_0: CheapScreen.

65. If positive branch

c1:HighFidelity.c_1: HighFidelity.

66. If failure branch

c2:CounterReplication.c_2: CounterReplication.

67. If transport promising

c3:RealExperiment.c_3: RealExperiment.

68. This Is Sequential Program


69. Hyperband External Calibration

Hyperband treats configurations as arms and allocates finite resources adaptively。


70. Early Stop Poor Configurations


71. WDC Difference

Poor performance world can still be valuable counterevidence。


72. Therefore Elimination Criterion Is Evidence Value, Not Performance Alone


73. Successive Evidence Escalation

L0L1L2L3L4.\boxed{ L_0\rightarrow L_1\rightarrow L_2\rightarrow L_3\rightarrow L_4. }

74. L0 Abstract Screening

cheap symbolic / analytical。


75. L1 Low-Fidelity World


76. L2 Replicated Medium Fidelity


77. L3 High Fidelity / Cross Backend


78. L4 External Test


79. Promotion Trigger

can be:

  • support;
  • counterexample;
  • disagreement;
  • tail risk;
  • transport value。

80. Not Positive Result Only


81. Multi-Fidelity External Calibration

Song et al. study different mutually dependent information sources with different costs。


82. Key Neighboring Idea

cost-sensitive information allocation across fidelities。


83. WDC Extension

world fidelities may differ in:

  • dynamics;
  • actor realism;
  • resolution;
  • backend;
  • observation detail。

84. Low Fidelity Reliability

ρtarget.\rho_{\ell\to target}.

85. Mikkola et al. Warning

unreliable lower-fidelity sources can worsen total optimization cost。


86. WDC Consequence

A cheap world family with bad transport can misallocate Governor budget。


87. Reliability-Aware Promotion


88. No Auto-Prune from Uncalibrated Low Fidelity


89. Epistemic Deficit

Δt(q).\Delta_t(q).

90. Why Deficit First?

Because same evidence count can hide different missingness。


91. Example A

1000 stochastic runs same backend。


92. Stochastic deficit small

δrun.\delta_{run}\downarrow.

93. Independence deficit high

δind.\delta_{ind}\uparrow.

94. Correct action

CrossBackend。


95. Wrong action

Run 1000 more seeds。


96. Example B

5 independent backends agree。


97. But no real calibration。


98. Transport deficit high。


99. Correct action

Calibrate。


100. Example C

Strong consensus, no counter search。


101. Counter deficit high。


102. Correct action

ForkCounter。


103. Example D

Model family known bad in rare tail。


104. Tail deficit high。


105. Correct action

StressTail。


106. Deficit-Directed Routing Table

δkOpk.\boxed{ \delta_k \rightarrow Op_k. }

107. This Can Be Learned

but initially rule-based。


108. Portfolio

ΠtW.\Pi_t^W.

109. Why Portfolio?

Because unknowns are plural。


110. One computation mode cannot cover all。


111. Support Budget

BS.B_S.

112. Counter Budget

BC.B_C.

113. Independence Budget

BI.B_I.

114. Replication Budget

BR.B_R.

115. Transport Budget

BT.B_T.

116. Fidelity Budget

BH.B_H.

117. Unknown Exploration

BU.B_U.

118. Tail Stress

BX.B_X.

119. Total

BS+BC+BI+BR+BT+BH+BU+BXBG.\boxed{ B_S+B_C+B_I+B_R+B_T+B_H+B_U+B_X \le B_G. }

120. Not Fixed Percentages


121. Adaptive Rebalance

Πt+1=RP(Πt,Δt,Yt).\Pi_{t+1}=\mathcal R_P(\Pi_t,\Delta_t,Y_t).

122. Portfolio Dependence

Even different modes can share same backend。


123. Need dependence penalty


124. Marginal Independence Gain

VX(c).V_X(c).

125. If Proposed World Is Near Duplicate

VX.V_X\downarrow.

126. But Replication Value May Still Be High

VR.V_R\uparrow.

127. Separate Them


128. Portfolio Diversity Is Functional

not visual diversity。


129. Cosmetic World Diversity

different prompts / colors。


130. Structural World Diversity

different error sources。


131. World-Mode Collapse

if all budget to one family。


132. But Anti-Mode-Collapse Can Overexplore


133. Need opportunity cost


134. Opportunity Cost

OC(c).OC(c).

135. Compare with next-best computation


136. A Positive Value Computation Can Still Be Suboptimal


137. Resource Knapsack View

finite resources:

B1,,Br.B^1,\ldots,B^r.

138. Each computation consumes vector cost。


139. Portfolio is constrained multi-resource selection


140. But outcomes adaptive

so static knapsack insufficient。


141. Sequential Policy

πC:Etct.\boxed{ \pi_C: \mathfrak E_t \rightarrow c_t. }

142. Computation Policy

This is Governor's meta-policy。


143. Myopic Policy

choose:

argmaxcVmyopic(c).\arg\max_c V^{myopic}(c).

144. Dynamic Policy

accounts downstream。


145. Exact Dynamic Planning Often Intractable


146. Bounded Approximation Needed


147. WDC Doesn't Promise Optimal Governor


148. Deadline

TD.T_D.

149. Slow high-value computation

may arrive after decision。


150. Value Decays


151. Deadline-Adjusted VOC

VOCDdeadline.VOC_D^{deadline}.

152. Result Latency Is First-Class


153. Parallelism

Can run several worlds simultaneously。


154. But parallel computations may become redundant after one finishes


155. Batch Value

V({c1,,ck})V( \{c_1,\ldots,c_k\} )

not necessarily additive。


156. Redundant Batch

two worlds answer same question。


157. Complementary Batch

one support, one counter, one transport。


158. Batch Scheduling

needs joint value estimate。


159. Diversity Reserve Helps


160. But Reserve Itself Costs compute


161. Tail-Risk Worlds

low probability/high impact。


162. Why Majority Scheduler Fails

posterior-low branches get no budget。


163. But safety may demand coverage。


164. Tail Utility

VR(c).V_R(c).

165. Domain-specific risk measure

Could be:

  • failure probability;
  • worst-case;
  • CVaR;
  • reachability risk。

166. WDC Does Not Mandate One


167. Safety-Critical Override

Some worlds computed due obligation

even if expected decision gain low。


168. Mandatory Compute

cCobligatory.\boxed{ c\in\mathcal C_{obligatory}. }

169. Example

minimum adversarial test before deployment。


170. Thus Portfolio Has Hard Constraints

not only utility optimization。


171. Decision Boundary Worlds

If two actions nearly tied,

compute worlds that discriminate。


172. Discriminative Value

Vdisc.V_{disc}.

173. If outcome distributions same under H1/H2

low discriminative value。


174. If strongly different

high value。


175. This Is Experimental-Design Logic


176. Scientific Hypothesis Testing

world can be chosen to maximize expected separation。


177. Not to maximize preferred hypothesis success。


178. Counterworld Design

Generate world where leading claim most likely fails

while remaining plausible。


179. Strongest Counterworld

W¬q=argmaxW{P(¬qW)×Validity(W)×Independence(W)}.\boxed{ W^\star_{\neg q} = \arg\max_W \{ P(\neg q\mid W) \times Validity(W) \times Independence(W) \}. }

conceptual only。


180. Avoid Unrealistic Strawman Counterworld


181. Counterworld Plausibility Contract

must remain inside admissible target assumptions。


182. Calibration World

world designed to test known real cases。


183. Its outcome is not new future prediction

but model credibility measurement。


184. Calibration Value

Vcal.V_{cal}.

185. Transport Value

related but not identical。


186. Calibration can reveal

  • systematic bias;
  • scale mismatch;
  • dynamics error。

187. Transport Debt Decomposition

from WDC-05:

DT.\mathbf D_T.

188. Choose computation targeting largest debt component。


189. Example

DagentD_{agent} high。


190. Need human behavior calibration

not higher physics fidelity。


191. Example

DdynD_{dyn} high。


192. Need better dynamics backend。


193. Therefore High Fidelity Must Be Typed


194. Fidelity Vector

F=(Fstate,Fdyn,Fagent,Frule,Ftime).\boxed{ \mathbf F = ( F_{state}, F_{dyn}, F_{agent}, F_{rule}, F_{time} ). }

195. Upgrade Relevant Coordinate Only


196. Don't pay for photorealism if claim about symbolic dynamics


197. Fidelity Waste

Cfidelityirrelevant.\boxed{ C_{fidelity}^{irrelevant}. }

198. World Portfolio Frontier

multi-objective frontier。


199. Governor can present frontier to master/human

rather than hidden scalar ranking。


200. Explain Allocation

For each selected computation:

selected because independence deficit high。


201. Explain Rejection

rejected as redundant with family F3。


202. Explain Pause

marginal stochastic precision below threshold。


203. Explain Promotion

strong counterexample needs high-fidelity replication。


204. Explain External Test

simulation robustness high; transport debt now dominant。


205. This Is More Auditable Than One Score


206. Meta-Calibration

Governor predicts:

V^(c).\widehat V(c).

207. After outcome

measure:

Vrealized(c).V^{realized}(c).

208. Store pair


209. Calibration Curve

predicted vs realized gain。


210. Governor Overconfidence

if predicted high, realized low。


211. Governor Underexploration

if killed computations later found valuable。


212. Governance Miss

from WDC-03。


213. WDC-06 Reuses Misses to Learn Computation Value


214. Archived World as Training Data

Governance history can train meta-policy。


215. But Avoid Self-Confirmation

if only executed computations have labels。


216. Selection Bias

unexecuted worlds have unknown realized value。


217. Need exploration audit

randomly sample some low-priority computations。


218. Off-policy Evaluation Difficult


219. Finite Benchmark Helps

where exhaustive tree known。


220. Benchmark A — Exhaustive Small Portfolio

all computations run。


221. Learn optimal allocation under budget。


222. Compare Governor regret。


223. Benchmark B — Information vs Decision

one high EIG irrelevant world。

one low EIG decision-flipping world。


224. Governor should distinguish。


225. Benchmark C — Independence Deficit

many same-family runs。

one independent backend。


226. Correct next compute = independent backend。


227. Benchmark D — Counterexample Deficit

strong consensus but no adversarial search。


228. Correct = counterworld。


229. Benchmark E — Transport Deficit

many simulations agree。

known real calibration absent。


230. Correct = calibration / real-test proposal。


231. Benchmark F — Unreliable Low Fidelity

cheap world misranks candidates。


232. Governor should learn low ρtarget\rho_{\ell\to target}


233. Benchmark G — Hyperband-Like Screening

many candidates, small cheap budgets。

promote informative subset。


234. Compare compute savings。


235. Benchmark H — Negative Result Promotion

cheap world finds critical failure。

should promote despite poor success metric。


236. Benchmark I — Tail Risk

rare catastrophic world with low probability。

ensure risk reserve。


237. Benchmark J — Deadline

accurate slow world vs coarser fast world。


238. Benchmark K — Meta-Overhead

VOC estimation expensive。

simple heuristic should win。


239. Benchmark L — Dynamic VOC

cheap screening unlocks valuable expensive experiment。

myopic policy misses it。


240. Benchmark M — Portfolio Redundancy

several computations look individually high-value but overlap heavily。


241. Benchmark N — World Family Expansion

all existing families share same assumption。

unknown-world exploration creates new family。


242. Benchmark O — Calibration World

world intentionally reproduces historical cases。

measure transport debt reduction。


243. Benchmark P — Governance Selection Bias

meta-policy trained only on executed worlds。

test random audit worlds reveal bias。


244. WDC-06 Principle I — Computation Unit

Computation Unit Principle\boxed{ \textbf{Computation Unit Principle} }

Governor allocation should target specific next computations, not attach permanent worth labels to worlds.


245. Principle II — Deficit-Directed Allocation

Deficit-Directed Allocation Principle\boxed{ \textbf{Deficit-Directed Allocation Principle} }

Choose computations according to the dominant unresolved evidence or decision deficit rather than automatically adding more runs to the leading world family.


246. Principle III — Information–Decision Separation

Information–Decision Separation Principle\boxed{ \textbf{Information–Decision Separation Principle} }

Expected information gain and expected decision improvement are distinct quantities and should be reported separately where both matter.


247. Principle IV — Portfolio Complementarity

Portfolio Complementarity Principle\boxed{ \textbf{Portfolio Complementarity Principle} }

The value of a world computation depends on what the current portfolio already contains; near-duplicate evidence has lower marginal independence value than genuinely complementary computation.


248. Principle V — Dynamic Computation

Dynamic Computation Principle\boxed{ \textbf{Dynamic Computation Principle} }

A computation can be valuable because it changes which later computations become worthwhile; next-computation value should not be assumed purely myopic.


249. Principle VI — Fidelity Reliability

Fidelity Reliability Principle\boxed{ \textbf{Fidelity Reliability Principle} }

Low-fidelity worlds should only be allowed to screen or terminate higher-fidelity computation to the extent that their relation to the target has been calibrated.


250. Principle VII — Tail Preservation

Tail Preservation Principle\boxed{ \textbf{Tail Preservation Principle} }

Low-probability worlds can retain high computation value when they probe catastrophic, irreversible, safety-critical, or highly discriminative regions.


251. Principle VIII — Transport First When Transport Is the Bottleneck

Transport-Bottleneck Principle\boxed{ \textbf{Transport-Bottleneck Principle} }

When cross-world robustness is already high but world-to-target transport debt dominates, additional simulation may be inferior to calibration or external testing.


252. Principle IX — Meta-Boundedness

Meta-Boundedness Principle\boxed{ \textbf{Meta-Boundedness Principle} }

Computing the value of computation has its own cost; WDC metareasoning must itself stop when additional allocation analysis is not worth its cost.


253. Principle X — Meta-Calibration

Meta-Calibration Principle\boxed{ \textbf{Meta-Calibration Principle} }

A Governor should compare predicted computation value with realized information, verification, transport, and decision gain, and update its allocation model over time.


254. 可否證條件

F254.1 Portfolio No-Gain

若 portfolio allocation 長期不優於簡單 equal / random / FIFO policies,WDC-06 應簡化。

F254.2 VOC Miscalibration

若 predicted VOC 與 realized decision improvement無關,decision-value model 需要重建。

F254.3 EIG Misuse

若高 EIG computations 持續不影響 target decisions,不能把 information gain 當 decision value proxy。

F254.4 Counterworld Waste

若 counterworld budget 只產生 unrealistic invalid failures,counterworld generator 需提高 admissibility。

F254.5 Independence Mispricing

若所謂 independent worlds 仍共享主要 error source, VXV_X 被高估。

F254.6 Low-Fidelity Misrouting

若 low-fidelity worlds frequently prune high-value high-fidelity worlds,reliability gate 失效。

F254.7 Dynamic-VOC Overhead

若 non-myopic computation planning成本大於其收益,應退回 myopic / heuristic policy。

F254.8 Tail Overallocation

若 tail reserve 消耗大量 budget、卻對安全或 decision 完全無增量,應調整。

F254.9 Transport Neglect

若 simulation consensus 不斷增加但 external calibration 始終不進行,portfolio 失衡。

F254.10 Meta-Selection Bias

若 Governor 只從已執行 computations 學習而忽略 rejected-world outcomes,meta-calibration 可能自我封閉。


255. 與 WDC-07 的接口

WDC-06 現在回答:

下一個 world computation 應該做什麼?

但還有下一個問題:

這些 world computations 做完後,系統如何真正學習?

如果每輪只是:

  1. spawn;
  2. run;
  3. aggregate;
  4. archive;

然後下一輪重新從零開始,

WDC 仍只是昂貴的 simulation factory。

下一篇:

WDC-07 — World Ensemble Learning

《世界集合學習:跨世界結果如何更新生成器、模型、Governor 與未來空間》

將研究:

Outcomes(Wt)Update(WorldGenerator,WorldModel,Governor,TCDFutureSpace).\boxed{ Outcomes( \mathcal W_t ) \rightarrow Update( WorldGenerator, WorldModel, Governor, TCDFutureSpace ). }

以及更危險的問題:

如果 Generator 只學自己以前生成的 worlds,會不會形成自我封閉的 world ontology?


256. 結論

WDC-03 問:

worlds 太多怎麼管理?

WDC-06 現在把問題再往前推:

管理的真正目標是什麼?

答案不是:

保留最多 worlds.\boxed{ \text{保留最多 worlds}. }

也不是:

永遠擴大目前最有希望的 world.\boxed{ \text{永遠擴大目前最有希望的 world}. }

真正 allocation unit 是:

c=next world computation.\boxed{ c = \text{next world computation}. }

而它的價值取決於:

現在已經知道什麼\boxed{ \text{現在已經知道什麼} }

與:

現在最缺什麼.\boxed{ \text{現在最缺什麼}. }

當 stochastic uncertainty 最大時:

多跑幾次。

當 independent evidence 不足時:

換 backend。

當 consensus 太舒服時:

找 counterworld。

當 tail risk 未知時:

stress-test。

當 transport debt 最大時:

停止增加模擬,去 calibration。

當兩個 hypotheses 都說得通時:

找最能區分它們的 world。

因此:

The most valuable world to compute next is the one with the highest marginal contribution to the current decision-and-evidence portfolio, not necessarily the world currently believed most likely to succeed.\boxed{ \textbf{The most valuable world to compute next is the one with the highest marginal contribution to the current decision-and-evidence portfolio, not necessarily the world currently believed most likely to succeed.} }

中文:

下一個最值得計算的世界,是對目前決策與證據投資組合具有最高邊際增量的世界,而不一定是現在最被看好的世界。

所以 WDC-06 真正把:

World-Domain Governor\boxed{ \text{World-Domain Governor} }

從一個 lifecycle / scheduler manager,

推成了:

World-Portfolio Metareasoner

它不再只問:

哪個 process 還有 GPU?

而問:

下一單位計算,放在哪裡最不浪費我們對未知世界的探索?\boxed{ \text{下一單位計算,放在哪裡最不浪費我們對未知世界的探索?} }

這也是 Branching World Computation 第一次真正碰到:

computation itself as a scarce epistemic action.\boxed{ \text{computation itself as a scarce epistemic action}. }

Claim Typing

Claim Type Status
World worth 與 next-computation value 非同一 D Canonical separation
WDC allocation unit 可定義為 typed world-computation action D Proposed core formalization
Decision VOC 與 EIG 非同一 D / E Core distinction + external metareasoning/BOED analogue

  • WDC 的 VOC vector 有 universal estimator;
  • EIG 是所有 science / engineering decisions 的最佳 utility;
  • Hyperband、BOED、MCTS 或 multi-fidelity BO 等同 WDC;
  • low-fidelity worlds 必然能省成本;
  • counterworlds 應獲固定比例算力;
  • tail-world budget 有跨 domain 通用最優值;
  • Governor 可以只靠自動 scoring 取代人類/制度 authority;
  • world portfolio metareasoning 已解決所有 normative research-priority 問題;
  • 本文對 classical PP vs. NPNP 提供任何新證明。

本文真正建立的是:

World Portfolio Allocation=choose the next computation under finite evidence and compute budgets.\boxed{ \text{World Portfolio Allocation} = \text{choose the next computation} \text{ under finite evidence and compute budgets}. }

以及:

Worth ComputingWorth BelievingWorth Deploying.\boxed{ \text{Worth Computing} \neq \text{Worth Believing} \neq \text{Worth Deploying}. }
