New algorithm tackles Nash equilibrium in complex multiplayer games · 3 sources tracked

By PulseAugur Editorial · [5 sources] ·

Researchers have developed a new algorithm called Projected Exploitability Descent (PED) for approximating Nash equilibria in complex multiplayer games with imperfect information. This algorithm minimizes a proxy for the exploitability function, which is a non-convex and non-smooth objective. While PED shows consistent improvement over long runs, it is initially outperformed by established methods like Fictitious Play (FP) and Counterfactual Regret Minimization (CFR). A hybrid approach, FP-PED, combines FP's initial efficiency with PED's long-term refinement capabilities, demonstrating improved performance on benchmarks like three-player Kuhn poker. AI

IMPACT This research could lead to more scalable and efficient computation of game equilibria, impacting AI agents in complex strategic environments.
