Research Abstract |
We conducted the research on technologies solving large-scale Constraint Satisfaction/Optimization Problems by combining SAT technologies and model generation technologies, and published 9 refereed papers and made 36 presentations. In addition, world’s leading softwares QMaxSAT and SCMiniSat were developed. QMaxSAT won at the 2010, 2011, and 2012 Max-SAT evaluations in an industrial category and SCMiniSat increased the lower bound of Ramsey number R(4,8) from 56 to 58.
