This is a Python 3 controller for my 4x4 Hex challenge on PPCG.
Usage (assuming your Python 3 command is python3):
python3 hex-controller.py
You can change the parameters within the script file, including the command of the script to be tested.
If your strategy is not winning, the controller will output a losing game.
Use the (incorrect) solution test.py to test the controller.
