set-cover: Solve exact set cover problems like Sudoku, 8 Queens, Soma Cube, Tetris Cube

[ algorithms, bsd3, library, math ] [ Propose Tags ]

Solver for exact set cover problems. Included examples: Sudoku, Nonogram, 8 Queens, Domino tiling, Mastermind, Soma Cube, Tetris Cube, Cube of L's, Logika's Baumeister puzzle. The generic algorithm allows to choose between slow but flexible Set from containers package and fast but cumbersome bitvectors.

For getting familiar with the package I propose to study the Queen8 example along with Math.SetCover.Exact.

Build examples with cabal install -fbuildExamples.

The package needs only Haskell 98.
