![]() That’s where the heuristic function comes in. Instead, there needs to be a way to evaluate how good the board is at any time and just try to get to a good place. That means that it’s incredibly expensive to try to look ahead to the end of the game and figure out how to get there. In mancala, though, there are 6 moves at any time and each move affects the remaining states of the game. In tic-tac-toe, there are at most 9 possible moves to be made at any given time, so it’s not unreasonable to examine all possible states of the game board. Minimax trees and AB pruning consider how good the board is for each player during their turn. The best move I consider is the only move the bot considers Here’s that example more visually (I’m X, the bot is O). How the bot thinksĪB pruning is a method of ignoring board states which will never occur (if the opponent also behaves like the bot).ĪB pruning assumes the following: if I’m playing a game of tic tac toe and there’s a move I can make that will make it possible for me to win, I will ignore all other moves so the bot making a decision can, too. It recurses n levels then returns the move which will eventually produce the most desirable board state. The bot uses a minimax tree to select the next move, meaning it chooses the move that will produce the best outcome assuming the opponent will do the same. My goal was to build a mancala bot that could beat both me and other mancala bots. This project was for Northwestern’s EECS 348. Here’s a writeup of general techniques and results.
