Sudoku is a very simple and well-known puzzle that has achieved international popularity in the recent past. This paper addresses the problem of encoding Sudoku puzzles into conjunctive normal form (CNF), and subsequently solving them using polynomial-time propositional satisfiability (SAT) inference ...
3.5 An Improved Algorithm for a Restricted Theory of Strings Unfortunately, it is unknown if the satisfiability problem of string constraints with length operations is decidable in general =-=[11, 18]-=-. This has a bearing on our algorithm in that it may not terminate for certain cases, ...

Indeed, given the universality classes of classical spin models, of which the Ising is probably the most emblematic example, they all can be mapped to distinct instances of the logic problem of satisfiability (SAT) [28]. In this way, the analytic solution of the 3D case conceivably would ...
