          <datacite:description descriptionType="Other">制約充足問題 (CSP) は与えられた制約を満たす解を探索する問題であり，多くの組合せ問題は CSP として定式化できる．SAT 型制約ソルバーは，CSP を命題論理の充足可能性判定問題 (SAT) に符号化し，SAT ソルバーを用いて探索することにより，CSP の解を求めるプログラムである．ここでは，国際的な競技会で優秀な成績を収めている制約ソルバー Sugar および SAT ソルバー GlueMiniSat を用い，SAT 型制約ソルバーでナンバーリンク問題の高速な求解が可能であることを示す．また，制約記述には Scala 上の制約プログラミングシステムであるCopris を用いる．これにより，提案するシステムは高い拡張性も実現している．</datacite:description>
          <datacite:description descriptionType="Other">Constraint Satisfaction Problem (CSP) is a problem to find a solution satisfying all given constraints, and many combinatorial problems can be formalized as a CSP. SAT-based constraint solver is a program to find a solution of a given CSP by encoding it to a Boolean satisfiability testing program (SAT) and searching a solution with a SAT solver. In this paper, we show a SAT-based constraint solver can efficiently solve Numberlink puzzles with Sugar and GlueMiniSat solvers which performed well at the international solver competitions. A constraint programming system Copris on a Scala programming language is used for a constraint modeling. Therefore, the proposed Numberlink solver also realizes high extensibility.</datacite:description>
