ORBIT WARS — GAME AI AGENT
SILVER · 175/4,729 · SOLO PLAY THE AGENT COMPETITIONFig. 1 — one intercept solve, looping. Same math as Fig. 0.
A fully vectorized PyTorch planning agent — ~5,500 LOC across 15 modules — that played thousands of live 500-turn adversarial ladder games inside a hard per-turn compute budget.
- Built an orbital trajectory-prediction engine that forward-simulates planet motion over an 18-turn horizon and solves intercept angles against planets rotating around a central sun.
- Paired it with an ETA-aware reinforcement-risk model that declines captures the opponent could reinforce mid-flight.
- Depth-2 expectimax with softmax opponent modeling for 1v1; a separately tuned game-theoretic policy for 4-player free-for-all.
- Prototyped behavioural-cloning and reinforcement-learning agents, benchmarked all three head-to-head on the ladder, and shipped the strongest.
