在约束满足博弈中,短序列的改进移动会导致近似均衡

Short sequences of improvement moves lead to approximate equilibria in constraint satisfaction games

Ioannis Caragiannis, Angelo Fanelli, Nick Gravin

摘要:

我们提出了一个算法,计算近似纯纳什均衡在广泛的一类约束满足游戏,推广了著名的削减和党派关系的游戏。我们的结果改进了Bhalgat等人的结果。(EC 10)在所获得的近似保证方面。更重要的是,我们的算法确定了一个多项式长序列的改进移动从任何初始状态的近似平衡,在这些游戏。这种短序列的存在是一种有趣的结构性质,据我们所知,这是以前所不知道的。我们的技术适应和扩展我们以前的工作拥塞游戏(FOCS 11),但目前的分析是相当简单。

英文摘要:

We present an algorithm that computes approximate pure Nash equilibria in a broad class of constraint satisfaction games that generalize the well-known cut and party affiliation games. Our results improve previous ones by Bhalgat et al.~(EC 10) in terms of the obtained approximation guarantee. More importantly, our algorithm identifies a polynomially-long sequence of improvement moves from any initial state to an approximate equilibrium in these games. The existence of such short sequences is an interesting structural property which, to the best of our knowledge, was not known before. Our techniques adapt and extend our previous work for congestion games (FOCS 11) but the current analysis is considerably simpler.
