约束对策的完全解

A Complete Solver for Constraint Games

Université de Caen(卡昂大学)

Thi-Van-Anh Nguyen, Arnaud Lallouet

摘要:

博弈论研究多个目标相互冲突的代理人必须达成集体决策的情况。代理效用函数的一个紧凑的表示语言的问题是至关重要的,因为一个$n$的球员游戏的经典表示是由一个$n$维矩阵的指数大小为每个球员。在本文中,我们使用的约束博弈的框架中,CSP被用来代表效用。约束编程-包括全局约束-允许轻松地为许多有用的游戏提供紧凑而优雅的模型。约束博弈有两种形式:约束满足博弈和约束优化博弈,第一种使用满足来定义布尔效用。除了多矩阵游戏,它也可以模拟更复杂的游戏,其中硬约束禁止某些情况。在本文中,我们研究了完整的搜索技术,并表明,我们的求解器使用的紧凑表示的约束游戏是快于经典的游戏求解器Gambit的一到两个数量级。

英文摘要:

Game Theory studies situations in which multiple agents having conflicting objectives have to reach a collective decision. The question of a compact representation language for agents utility function is of crucial importance since the classical representation of a $n$-players game is given by a $n$-dimensional matrix of exponential size for each player. In this paper we use the framework of Constraint Games in which CSP are used to represent utilities. Constraint Programming --including global constraints-- allows to easily give a compact and elegant model to many useful games. Constraint Games come in two flavors: Constraint Satisfaction Games and Constraint Optimization Games, the first one using satisfaction to define boolean utilities. In addition to multimatrix games, it is also possible to model more complex games where hard constraints forbid certain situations. In this paper we study complete search techniques and show that our solver using the compact representation of Constraint Games is faster than the classical game solver Gambit by one to two orders of magnitude.
