Outline of Final Research Achievements

We study various topics concerning with data compression and knowledge discovery, from both theoretical and practical points of view. We made several contributions on compressed string processing, string matching, combinatorial properties on the repetitive structures in strings, multi-agent system, computational learning theory, reinforcement learning, game analysis, and practical applications.
