Hi,
I've reading this forum for long time now, but this is my first post here  ,
I've recently started to programing a sudoku solver, programmed some of the basic techniques:
- Naked Subsets
- Hidden Subsets
- Pointing and Box/Line Reduction
- X-Wing, SwordFish and Jellyfish (non-Finned, Finned and Sashimi)
- XY-Wing
- Simple Coloring (Type: 1 and 2)
- X-Cycles (Tipe 1,2 and 3: Rules of NiceLoops)
- XY-Chain
- Aligned Pair Exclusion (Type: 1 and 2)
- Forcing Chains
- AIC
Now I planning to do ALS-ZX and the other until AIC-ALS, but I having a problem, I can't find an eficient way to find a single Almost Locked Set, if some can give-me a light on the mather that would be great!
btw: I'm programing in Visual Basic, and the structure use to save the gird is a matrice (8 by 8) of Integers (16 bits) in Bitwise |
