Sudoku analysis and generation C# program. The only algorithm used is non-backtracking. The algorithm used is Single, LockedCandidate, (hidden)LockedSet(2D-7D), (Finned)(Franken/Mutant/Kraken)Fish(2D-7D), Skyscraper, EmptyRectangle, XY-Wing, W-Wing, RemotePair, XChain, XYChain, SueDeCoq, (Multi)Coloring, ALS-Wing, ALS-XZ, ALS-Chain, (ALS)DeathBlossom(Ext.), (Grouped)NiceLoop, ForceChain and GeneralLogic. There are also functions for transposed transformation of Sudoku problems, standardization and ordering of Sudoku problems. The algorithm is explained on the HTML page.
