Hi Erel,Your result is a good result for a pure backtracking solution.
Backtracking can be a very heavy operation. You should try to think of ways to "help" the backtracking operation (somehow make the puzzle easier for example).
The idea is to use less "brute force" and find ways to decrease the puzzle complexity.What did you mean with "(somehow make the puzzle easier for example)" ?
Hi Erel,The deadline is today at 23:59 PM...

I will post the set of puzzles.Is it possible to get later the puzzle set you will use to test the solvers ?
