Everything else

What do A.A. Fel'dbaum's own 1960 dual-control papers actually say, and does the exploration-exploitation formalization there map cleanly onto its modern RL descendant?

Fel'dbaum's own exact Bayesian dynamic-programming solution to dual control is one he himself flagged as impractical beyond small examples, confirmed by two independent later sources

Fel'dbaum's own 1960 dual control papers decompose control risk into an additive "risk of action" and "risk of study"

Mainstream RL's exploration algorithms trace to an independent 1933 bandit lineage, not to Fel'dbaum's dual control theory; his formalism maps cleanly only onto Bayesian reinforcement learning

Does Åström's own 1965 POMDP paper anticipate agent-decision-making use, or does the 2026 LLM-agent resurfacing read the anticipation in backwards?

Åström's 1965 paper's own Notes section places it in a Bellman–Fel'dbaum–Pontryagin–Kolmogorov control-theory lineage, directly citing A.A. Fel'dbaum's 1962 paper

The cosine-0.87 pairing between the vault's Puckette 'buried common-ancestor bridge' note and its Pitman/Fel'dbaum 'same genre, opposite tool outcomes' note is an embedding false friend — shared genre, no object-level bridge

What genuinely connects the Puckette/fourth-instance-hedged-bridge pairing (a buried common-ancestor bridge) and the Pitman/Feldbaum pairing (same genre, opposite tool outcomes) — cosine 0.87

Åström's 1965 control-theory paper, cited as reference [1] in AI's founding POMDP paper (1998), is the same math object 2026 papers use to formalize LLM-agent decision-making

What genuinely connects the Isaac Pitman/Gabelsberger-IPA bridge and the A.A. Fel'dbaum/Song-Jian-Kalman bridge (cosine 0.87): one shared genre, two opposite tool outcomes

The Isaac Pitman/Gabelsberger-IPA bridge and the A.A. Fel'dbaum/Song-Jian-Kalman bridge are both genuine person-bridges but represent opposite `vault_bridge` outcomes, not the same blind spot

A.A. Fel'dbaum — Song Jian's Soviet control-theory teacher — originated the mathematical ancestor of reinforcement learning's exploration-exploitation tradeoff

A.A. Fel'dbaum's early-1960s dual control theory was the first mathematical formalization of the exploration-exploitation tradeoff
