Their work included designing and integrating a 50/50 Cats AI strategy, which targets optimal move selection in cat’s game scenarios to improve endgame outcomes. All contributions were clearly documented with descriptive commit messages, supporting maintainability. The project demonstrated depth in both algorithmic design and code organization, though the scope was limited to a single feature.
