Tsinghua University introduced the AAArena benchmark to evaluate heuristic learning in AI coding agents within long-running game competitions. The study reveals that detailed match replay feedback significantly outperforms win/loss-only signals, propelling a Pacman bot from rank 11 to rank 1; however, tripling the match budget failed to help stuck agents overcome limitations in games with complex rules.

    • The AAArena benchmark features 12 games and 1,920 archived human programs as opponents, simulating a realistic dynamic competitive environment.
    • Coding agents evolve strategies by reading rules, selecting opponents, analyzing replays, and rewriting code without altering model weights.
    • Detailed match replays provide crucial context for performance improvement, whereas simply increasing interaction counts (match budget) fails to resolve learning stalls in complex-rule games.
