This project is a four in row game (player vs computer) that has been written in C++ The algorithm that I used is min-max algorithm after that I have added alpha-beta functionality to reduce the number of node generated. In this project the user able to set the depth since the algorithm uses depth-first search. choosing depth to be 7 is the best in terms of memory performance, which consume around 25M. ///////////////////// program running ///////////////////// 0: you play first, 1 computer play first: 0 enter max depth: 7 | | | | | | | | | | | | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 3 | | | | | | | | | | | X | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 3 Created Nodes: 269273 | | | | | | | | | O | | X | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 2 | | | | | | | | | O | | X X | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 4 Created Nodes: 306588 | | | | | | | | | O | | X X O | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 3 | | | | | | | X | | O | | X X O | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 3 Created Nodes: 399407 | | | | | O | | X | | O | | X X O | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 1 | | | | | O | | X | | O | | X X X O | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 0 Created Nodes: 555803 | | | | | O | | X | | O | | O X X X O | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 1 | | | | | O | | X | | X O | | O X X X O | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 3 Created Nodes: 358062 | | | O | | O | | X | | X O | | O X X X O | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 3 | X | | O | | O | | X | | X O | | O X X X O | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 1 Created Nodes: 183494 | X | | O | | O | | O X | | X O | | O X X X O | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 0 | X | | O | | O | | O X | | X X O | | O X X X O | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 1 Created Nodes: 156003 | X | | O | | O O | | O X | | X X O | | O X X X O | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 6 | X | | O | | O O | | O X | | X X O | | O X X X O X | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 0 Created Nodes: 146830 | X | | O | | O O | | O O X | | X X O | | O X X X O X | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 5 | X | | O | | O O | | O O X | | X X O | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 0 Created Nodes: 150281 | X | | O | | O O O | | O O X | | X X O | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 0 | X | | X O | | O O O | | O O X | | X X O | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 0 Created Nodes: 133756 | O X | | X O | | O O O | | O O X | | X X O | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 6 | O X | | X O | | O O O | | O O X | | X X O X | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 1 Created Nodes: 41517 | O X | | X O O | | O O O | | O O X | | X X O X | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 1 | O X X | | X O O | | O O O | | O O X | | X X O X | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 2 Created Nodes: 10302 | O X X | | X O O | | O O O | | O O X | | X X O O X | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 your turn, type a column number: 2 | O X X | | X O O | | O O O | | O O X X | | X X O O X | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 computer is thinking ... computer played: 2 Created Nodes: 5399 | O X X | | X O O | | O O O O | | O O X X | | X X O O X | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 | O X X | | X O O | | O O O O | | O O X X | | X X O O X | | O X X X O X X | - - - - - - - 0 1 2 3 4 5 6 Red won!
