前缀独立目标并发对策的子对策最优策略

Sub-game optimal strategies in concurrent games with prefix-independent objectives

Benjamin Bordais, Patricia Bouyer, Stéphane Le Roux

摘要:

研究了目标前缀独立的有限图上的并发两人赢/输随机博弈。我们刻画了子博弈最优策略,并利用这个刻画来展示各种记忆转移结果:1)对于给定的(前缀无关的)目标,如果每个具有子博弈几乎肯定获胜策略的博弈也有位置策略,那么每个具有子博弈最优策略的博弈也有位置策略; 2)假设(前缀无关的)目标具有中性颜色。如果每个回合制博弈都有一个子博弈几乎必胜策略,也有一个位置策略,那么每个有有限选择(概念有待定义)子博弈最优策略的博弈也有一个位置策略。我们收集或设计的例子,以表明我们的结果是紧在几个方面。我们还将我们的结果应用于Büchi,co-Büchi,平价,平均收益目标,从而得到更简单的陈述。

英文摘要:

We investigate concurrent two-player win/lose stochastic games on finite graphs with prefix-independent objectives. We characterize subgame optimal strategies and use this characterization to show various memory transfer results: 1) For a given (prefix-independent) objective, if every game that has a subgame almost-surely winning strategy also has a positional one, then every game that has a subgame optimal strategy also has a positional one; 2) Assume that the (prefix-independent) objective has a neutral color. If every turn-based game that has a subgame almost-surely winning strategy also has a positional one, then every game that has a finite-choice (notion to be defined) subgame optimal strategy also has a positional one. We collect or design examples to show that our results are tight in several ways. We also apply our results to Büchi, co-Büchi, parity, mean-payoff objectives, thus yielding simpler statements.
