Description
Train the smallest possible neural network (fewest learnable parameters) that can predict optimal moves for 4x4 gravity Connect-3 positions with at least 95% accuracy on a hidden test set. The training data contains board positions labeled by an exact minimax solver, and only NumPy and PyTorch may be used.
