Complexity-Aware Symbolic Solvers for Sudoku: Towards Interpretability and Cognitive Alignment in Constraint Problem Solving
2025-12-22
Abstract excerpt
<title>Abstract</title> <p>SAT and Constraint Programming (CP) remain the fastest exact Sudoku solvers, on average taking milliseconds to solve even hard puzzles. They are, however, black-box optimizers and hence lack symbolic interpretability. The present article describes a complementary deterministic approach that explains reasoning with four symbolic solvers: Dynamic Constraint Propagation Backtracking (DCPB)...
