Outline of Final Research Achievements

SAT-based systems utilizing SAT solving technologies have been succeeding in various fields requiring highly efficient inference. In order to extend the SAT technology beyond its current application area, we conducted the research and development of SAT-based constraint programming systems in the following topics: (A) Extention to temporal logic, (B) Extention to multi-objective optimization problems, (C) Parallel solvers, and (D) Research and Development of application systems. As a result, we obtained several good accomplishments, such as winning at the international constraint solver competition, and solving problems which have not been solved with previous methods.
