In stochastic games, the player’s payoff is a variable. most papers, expected considered as payoff, which means risk neutrality of players. However, there may exist risk-sensitive players who would take into account “risk” measuring their payoffs. paper, we propose model games with mean-variance functions, sum expectation and standard deviation multiplied by coefficient characterizing attention...

In this paper, a constrained mean-variance model is constructed for the portfolio optimization problems. The model is a mixed quadratic integer programming problem, and it is too hard to solve by using the traditional optimal algorithms. The purpose of this paper is to use a heuristic algorithm to solve this problem. Combined with the differential evolution strategy, a new hybrid artificial bee...
