原始-对偶动态随机规划:平均场对策方法

Stochastic Programming with Primal-Dual Dynamics: A Mean-Field Game Approach

Casper T. Röling, Dario Bauso, Hamidou Tembine

摘要:

本研究针对容量网路设计之随机规划问题,探讨原始-对偶动力学。它被证明是可以实现共识的\textit{here and now}变量,代表网络的能力。主要贡献是一个启发式的方法,涉及制定的问题作为一个平均场游戏。平均场博弈中的每个代理都可以控制自己的原始对偶动态,并根据通信拓扑与相邻代理寻求共识。我们得到了关于平均场平衡存在的理论结果。此外,我们证明了共识动力学收敛,使代理同意各自的微网络的能力。最后,我们强调如何控制和状态的处罚影响的动力学代理的平均场游戏。

英文摘要:

This study addresses primal-dual dynamics for a stochastic programming problem for capacity network design. It is proven that consensus can be achieved on the \textit{here and now} variables which represent the capacity of the network. The main contribution is a heuristic approach which involves the formulation of the problem as a mean-field game. Every agent in the mean-field game has control over its own primal-dual dynamics and seeks consensus with neighboring agents according to a communication topology. We obtain theoretical results concerning the existence of a mean-field equilibrium. Moreover, we prove that the consensus dynamics converge such that the agents agree on the capacity of their respective micro-networks. Lastly, we emphasize how penalties on control and state influence the dynamics of agents in the mean-field game.
