AI agent achieves 51.35% win rate against champion using unsound search

Researchers have developed an agent for the collectible card game Legends of Code and Magic that utilizes unsound search techniques to achieve a win rate of 51.35% against the game's champion, ByteRL. This agent, named NeteaseOPD, was trained using imitation learning and a policy and value feed-forward network, and it demonstrated a significant improvement of +24.6 percentage points in win rate when search was incorporated. Furthermore, the agent showed increased resilience against a published best-response attack compared to ByteRL. AI

IMPACT Demonstrates that unsound search can be effective in complex imperfect information games, potentially influencing future game AI development.
