Security solutions for two stage games, where the second stage consists of a strategic form noncooperative game, are not reachable in many problems. The aim of this paper is to investigate such solutions. Mixed extension for the second stage game is considered and existence results for approximate mixed security solutions, together with the convergences of values, are given and illustrated by significative examples. The results apply to the class of quasi harmonic games.

Stackelberg-Nash平衡和拟谐波博弈

在许多问题中都无法实现针对第二阶段游戏的安全解决方案，其中第二阶段包括战略形式的非合作游戏。本文的目的是研究这样的解决方案。考虑了第二阶段博弈的混合扩展，并通过有意义的示例给出和说明了近似混合安全解决方案的存在结果以及值的收敛性。结果适用于一类拟谐波博弈。
