Minecraft as AI Playground and Laboratory
summary
Minecraft serves as an open, diverse testbed with ~100 million monthly users and an open‑source platform called Project Malmo that lets researchers plug in agents, run tabular Q‑learning (converging in ~10 minutes on a cliff task) or pixel‑based deep RL to navigate lava rooms, train platformer agents, and probe collaboration. A new effort, the MineRL competition, mandates obtaining a diamond under strict limits using sample efficient reinforcement learning and large human demonstration sets; reported gains include ~70% success on one‑room mazes and ~15% on three‑room mazes.
