A new method was developed to help players in games find the best strategies without needing to know all the details of the game. Instead of using complex calculations, players only need to focus on their own rewards. This method uses a technique called "extremum seeking" with wavy patterns to figure out the best moves. The study looked at games where players aim to maximize their rewards in ways that aren't simple. The results show that this method can help players get close to the best strategies, even if they don't reach them perfectly. The accuracy of the results depends on how big the wavy patterns are and how complicated the rewards are.
