hi...

can anyone light me on an algorithm to solve sudoku...actually i did solve a few sudokus to know how this is done. Eventhough i managed to do the sudokus by paper and pencil, i can't figure out an algorithm to solve it. I googled for algorithms but everything ends up with graph colouring which i don't know ( i could only understand this: adjacent nodes are to be coloured differently ). Please someone help.
