Constraint satisfaction - Wikipedia

Constraint satisfaction problems on finite domains are typically solved using a form of search. The most used techniques are variants of backtracking, constraint propagation, and local search. These techniques are used on problems with nonlinear constraints.

Variable elimination and the simplex algorithm are used for solving linear and polynomial equations and inequalities, and problems containing variables with infinite domain. These are typically solved as optimization prob...

PicoSAT
The SAT problem is the classical NP complete problem of searching for a satisfying assignment of a propositional formula in conjunctive normal form (CNF). General information on SAT can be found at www.satlive.org or www.satlib.org. Our invited talk A Short History on SAT Solver Technology and What is Next? describes some of the new features of PicoSAT. The experimental data used in this talk is available as Biere-SAT07-talk-

Sudoku solving the easy way using boolean satisfiability » Luke's Blog
One of my recent interests has been in solving problems with various kinds of satisfiability solvers. As an introduction to this idea I want to demonstrate how to create a sudoku solver with almost no effort by reduction to a common satisfiability problem (CNF-SAT) and using an existing solver (MiniSat).

Solving Every Sudoku Puzzle
The function parse_grid calls assign(values, s, d). We could implement this as values[s] = d, but we can do more than just that. Those with experience solving Sudoku puzzles know that there are two important strategies that we can use to make progress towards filling in all the squares:

Which are the 2 solutions to this specific Sudoku puzzle. Running after changing the puzzle also solves the modified puzzle. Giving an empty puzzle (all _), the program will print every possible completed sudoku puzzle. However, that might take a while.
