Solving Sudoku Puzzles using PileExclusion

votes

I was trying to solve sudoku puzzle. My algorithm uses PileExclusion to remove the possibilities for each node. On certain puzzles am able to get the answer with 1 possible value for each node. On certain others I get one possible answer for most nodes but on certain nodes i have more than one possible value(which are the right ones) . Are there any other optimizations to further reduce the answer ?or should i make assumptions on certain values ?

There are many other techniques for excluding values. I recently ran into this page:
