Researchers have developed a new approximate policy-iteration algorithm designed for finite-horizon zero-sum partially observable stochastic games (zs-POSGs). This method maintains a policy for each player and updates them jointly, focusing computation on exploitable occupancy regions. The algorithm alternates between local policy improvements, conservative updates, and persistent exploration, showing competitive performance on benchmarks and often improving the runtime-exploitability trade-off compared to existing solvers like PBVI, HSVI, and CFR+.
