This is an experimental brute-force AI to play the game Quarto, e.g. https://boardgamearena.com/gamepanel?game=quarto .
To build the C++ code, use CMake and point it at the c directory. For now, this builds a command-line program call mquarto that plays a game with itself. Parameters may be tweaked in the code to change the board size and number of players, and/or allow one or more human players into the game.
