A Game-Theoretic Genetic Algorithm for the Competitive Facility Location Problem
We introduce a new evolutionary algorithm called the Game-Theoretic Genetic Algorithm (GTGA) for solving combinatorial optimization game theory problems where it is computationally infeasible to enumerate all decision options of the players involved in the game. Although evolutionary algorithms are widely used in combinatorial optimization, their applications to game theory have been limited to a specific type of games. The GTGA aims to handle different types of games using multiple populations and alternating fitness evaluation methods. We demonstrate an application of the GTGA to the Competitive Maximal Covering Location Problem, which is typically modeled as a two-player Stackelberg game such that first one player and then the other locate a fixed number of facilities to capture a maximum amount of revenue in a region. Computational experiments demonstrate that the GTGA can converge to Stackelberg, Nash, and minimax equilibria as well as outperform some existing approaches.
