Projects

FactorioRL | GitHub | Reinforcement Learning, Simulation, Sim-to-Game Transfer – Built a tick-exact Factorio simulator at 947k decisions/sec on 16 CPU threads (∼3,600× the real engine) with trace-level parity, driving RL training at 26,800 steps/sec on an RTX 4060.

– Transferred simulator-trained policies to the real game: agents trained only in simulation reach 90.6% success on unseen scenes in real Factorio, and held-out success on two build tasks rose from under 2% to 87–95%.
