Abstract

Sokoban is a game with simple rules, but finding solutions is a hard task for both people and computers. Sokoban is a NP-hard problem, which means that we probably cannot find every optimal solution in polynomial time. Instead, we must check all possible states in order to find the optimal solution. Thus, search algorithms are used for solving Sokoban. If we want to find a solution in a reasonable time, we need to find and implement good heuristics. Of course, because Sokoban is NP-hard, even the best current algorithms cannot find solutions to all Sokoban puzzles. The theoritical part of the thesis is analysis of the Sokoban problem and NP-hard problems. Practical part consists of description of our algorithm. We also tested our algorithm and compared it to a well-known algorithm JSoko.
