New PGTS framework enhances multi-agent game strategy computation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel framework called Primitive-Guided Tree Search (PGTS) to address the complexities of computing Nash equilibrium policies in multi-agent Pursuit-Evasion games. This hybrid approach combines offline computation of exact Nash equilibria for smaller sub-games with online tree search during deployment. PGTS utilizes these pre-computed optimal sub-game policies and value functions to guide its search and estimate leaf-node values, outperforming existing learning and heuristic methods in experiments across various graph topologies.

    Offline Nash Solvers Meet Online Tree Search in Multi-Agent Games on Graphs

    Computing Nash equilibrium policies in multi-agent Pursuit-Evasion games (PEG) is challenging due to the exponential growth of the joint state and action spaces with the number of agents. Existing approaches either rely on offline equilibrium approximations, which may lack adapta…
