摘要翻译：
最优性的概念自然地出现在应用数学和计算机科学的许多与决策有关的领域。在这里，我们在两种形式化的背景下考虑这个概念，这两种形式化用于不同的目的和不同的研究领域：图形游戏和软约束。本文将软约束满足问题中的最优性概念与图形博弈中的最优性概念联系起来，证明了对于一大类包含加权约束的软约束满足问题，每个最优解都对应于一个纳什均衡，这也是一个帕累托有效的联合策略。

英文摘要：
  The notion of optimality naturally arises in many areas of applied mathematics and computer science concerned with decision making. Here we consider this notion in the context of two formalisms used for different purposes and in different research areas: graphical games and soft constraints. We relate the notion of optimality used in the area of soft constraint satisfaction problems (SCSPs) to that used in graphical games, showing that for a large class of SCSPs that includes weighted constraints every optimal solution corresponds to a Nash equilibrium that is also a Pareto efficient joint strategy.
