Proper equilibrium further refines Reinhard Selten's notion of a trembling hand perfect equilibrium by assuming that more costly trembles are made with significantly smaller probability than less costly ones. ==Definition== Given a normal form game and a parameter $\backslash epsilon\; >\; 0$, a totally mixed strategy profile $\backslash sigma$ is defined to be $\backslash epsilon$-proper if, whenever a player has two pure strategies s and s' such that the expected payoff of playing s is smaller than the expected payoff of playing s' (that is is at most $\backslash epsilon$ times the probability assigned to s'. A strategy profile of the game is then said to be a proper equilibrium if it is a limit point, as $\backslash epsilon$ approaches 0, of a sequence of $\backslash epsilon$-proper strategy profiles. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Proper equilibrium」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
