Abstract (in Japanese) (See Japanese page) 
(in English) We develop a solver of board game Trax. Our basic strategy is a common game tree search algorithm. We explore the best move by the alpha-beta pruning. The game tree search is required evaluation function of some sort. we create it by machine learning. Usually this function is made by machine learning based on game record data of expert, but in this game, there is not enough game record data. Therefore, we make the evaluation function by machine learning based on the winning percentage by the Monte Carlo tree search. The search possible number of nodes is small in software-only solver. So we implement a partial of it on FPGA(Field Programmable Gate Array) for acceleration. The solver was about 10 times faster than a software-only solver.
