具有非凸费用函数的Nash-Cournot均衡模型的分裂邻近点方法

A splitting proximal point method for Nash-Cournot equilibrium models involving nonconvex cost functions

Tran Dinh Quoc, Le Dung Muu

摘要:

与凸情形不同,非凸Nash-Cournot寡头均衡问题的局部平衡点不一定是全局平衡点。找到这样一个局部的平衡点甚至是这个问题的一个稳定点并不是一件容易的事。本文讨论了具有非凸费用函数的Nash-Cournot均衡模型的一种数值方法。我们发展了一个局部方法来计算这类问题的一个稳定点。证明了算法的收敛性,并在一定的假设下估计了算法的复杂度。数值例子来说明所提出的算法的收敛行为。

英文摘要:

Unlike convex case, a local equilibrium point of a nonconvex Nash-Cournot oligopolistic equilibrium problem may not be a global one. Finding such a local equilibrium point or even a stationary point of this problem is not an easy task. This paper deals with a numerical method for Nash-Cournot equilibrium models involving nonconvex cost functions. We develop a local method to compute a stationary point of this class of problems. The convergence of the algorithm is proved and its complexity is estimated under certain assumptions. Numerical examples are implemented to illustrate the convergence behavior of the proposed algorithm.
