A Parallel Extended SAT Solver for Cardinality Constraints
XiaoJuan Xu, Yuji Yamane, Kazunori Ueda (Waseda Univ.) DC2011-17
Abstract (in Japanese) (See Japanese page) 
(in English) Cardinality constraints generated from real-world problems are often a bottleneck of SAT solving. This paper proposes an extended CNF that can express cardinality constraints and allows high-performance unit prop- agation. We have implemented it on MiniSAT 2.2 which is one of the most popular SAT solvers,by improving deduction and propagation mechanisms to handle the extended CNF.Furthermore,we have parallelized it for larger-scale CNFs. To evaluate the performance improvement over the original MiniSAT,we made an experiment on our parallel extented solver using the ITC2007 benchmark set that contains cardinality constraints problems.
