Explanation statuses — Whether the record believes the ACCOUNT, which is not what the same word means on a practice. An explanation can be Rejected while the thing it explained goes on working exactly as well as it ever did (ADR-031).

Replaced — a later account covers the same ground better, and this one names it.

THEORY-964 v3The minimax regret of a finite partial-monitoring game takes one of four rates, decided by its loss and signal matrices: 0 when only one action is non-dominated, Θ̃(√T) when every pair of neighbouring actions is locally observable, Θ(T^2/3) when the game is globally but not locally observable, and Θ(T) when it is not globally observable; against stochastic opponents for every game, against oblivious adversaries for non-degenerate gamesBartók, Foster, Pál, Rakhlin and Szepesvári (2014), LIT-1528, read in NOTE-1164. Four classes, trivial, easy, hard and hopeless, with conditions checkable from the matrices before play. It classifies the best policy for a fixed, known game. It does not cover a policy that is barred from some actions, a feedback structure that changes during play, or finite-horizon constants, and its adversarial half excludes degenerate games.Superseded — by THEORY-963
