There are 10 open issues and 12 have been closed. The artificial intelligence algorithms able to strongly solve Connect Four are minimax or negamax, with optimizations that include alpha-beta pruning, move ordering, and transposition tables. This readme documents the process of tuning and pruning a brute force minimax approach to solve progressively more complex game states. HTML and JavaScript, using jQuery. Two additional board columns, already filled with player pieces in an alternating pattern, are added to the left and right sides of the standard 6-by-7 game board. Also any suggestions to improve the readability of the code will be appreciated. For instance, each algebra word problem solver of ours is a math whiz. I want the bot to not automatically remove like that so the user can interact easily. why can my Circle not be found or why is value null?
