Core idea: The action decision or the value function can also be described in a continuous form, approximated by a nonlinear function in neural networks.Time and space complexity growing exponentially with search depth.It just obeys the rule which is made before, and could not be improved by playing. It can not learn anything while playing Gomoku.Static evaluation function always requires complicated artificial design and it needs a lot of time to consider plenty of situations.Use alpha-beta pruning to speed up the game tree search.Based on the min-max tree combined with a evaluation function of leaf board situations.We weight the two winning rates to select the action position with the maximum one. The ADP and MCTS methods are used to estimate the winning rates respectively.MCTS algorithm is based on Monte Carlo simulation method, which goes through lots of simulations and generates a game search tree.We combine a shallow neural network, which is trained by Adaptive Dynamic Programming ( ADP), with Monte Carlo Tree Search ( MCTS) algorithm for Gomoku.Leverage advanced regularization skills for temporal difference (TD)-LearningĪDP with MCTS Algorithm for Gomoku Methods Take away message.Extract more features by expert knowledge.focus on developing good heuristic functions which are mainly inspired by human players strategy as evaluation function to speed up the computation.Tree search based approach with alpha beta pruning implemented.Source Code: Github here Methods Take away message Paper Note CS221 Project Final Report Gomoku Game Agent No deep neural network (shallow is okay but needs to be less than 5 MB).Uploading file may not take more than 5 MB of space (zipped together with all necessary files) named as id.zip.With perfect play, either the first player wins or the result is a draw.īalanced opening from a set: AI and us has the same opportunity to be the first player.ġ5 seconds per move, 90 seconds per match for maximum In any size of a board, freestyle gomoku is an m, n, k-game, and it is known that the second player does not win.Free-style gomoku requires a row of five or more stones for a win. MASTER OF GOMOKU FREEGomoku Rule: Free Gomoku Rule(five or more).The winner is the first player to get 5 of their stones in a row, either vertically, horizontally or diagonally. The rules for Gomoku are similar to Go, where two players place stones alternatively on the intersections of the board. Gomoku, also know as five-in-a-row, is a strategy board game which is traditionally played with Go pieces on a go board with 15 × 15 intersections. The scope of this project is develop an AI agent for Gomoku. This is a note about implementing the final project of my Artificial Intelligence course. Effective Monte-Carlo Tree Search Strategies for Gomoku AI.CS221 Project Final Report Gomoku Game Agent.
