Making Catanatron Bot Stronger

The best bot right now is Alpha Beta Search with a hand-crafted value function. One of the most promising ways of improving Catanatron is to have your custom player inhert from (AlphaBetaPlayer) and set a better set of weights for the value function. You can also edit the value function and come up with your own innovative features!
