Fictitious Play for Mixed Strategy Equilibria in Mean Field Games: Abstract and Introduction | HackerNoon
Briefly

This paper examines mean field games with optimal stopping, addressing the complexity of coupled obstacle and Fokker-Planck equations which differ from classic models.
The proposed generalized fictitious play algorithm computes OSMFG mixed equilibria by solving pure strategy systems, effectively enabling agents to make optimal exit decisions.
Numerical experiments highlight the efficiency of the new method in robustly computing mixed equilibria for OSMFGs, demonstrating significant advancements in strategic interaction modeling.
The generalized fictitious play introduces a variety of learning rates while ensuring convergence to mixed strategy equilibrium, enhancing the understanding of agent decision-making.
