After 10 games, my Connect 4 program had accumulated 3 wins, 3 ties, and 4 losses. MinMax algorithm - Solving Connect 4: how to build a perfect AI During the development of the solution, we tested different architectures of the neural network as well as different activation layers to apply to the predictions of the network before ranking the actions in order of rewards. GitHub Repository: https://github.com/shiv-io/connect4-reinforcement-learning. The first player to connect four of their discs horizontally, vertically, or diagonally wins the game. >> endobj /Type /Annot /Border[0 0 0]/H/N/C[.5 .5 .5] Copy the n-largest files from a certain directory to the current one. /A << /S /GoTo /D (Navigation55) >> It also controls the overall game flow, which is to check if there is a winner (4 in a line) and notifies the user about the game status, and then it will reset the game for another round. Initially, the game was first solved by James D. Allen(October 1, 1988), and independently by Victor Allistwo weeks later (October 16, 1988). In this video we take the connect 4 game that we built in the How to Program Connect 4 in Python series and add an expert level AI to it. Let us take the maximizingPlayer from the code above as an example (From line 136 to line 150). This is where bitboards really come into their own - checking for alignments is reduced to a few bitwise operations. /Type /Annot The solver has to check for alignments of 4 connected discs after (almost) every move it makes, so it's a job that's worth doing efficiently. Connect Four - Wikipedia Here is the main function: Check the full source code corresponding to this part. Lower bound transposition table Part 7 - Transposition Table the initial algorithm was good but I had a problem with memory deallocation which I didn't notice thanks for your answer nonetheless! so which line is the index bounds errors occuring on? /A << /S /GoTo /D (Navigation55) >> Hence, we get the optimal path of play: A B D I.
