Hmm. In a 36x36, using your solution, the top left 6x6 grid would contain multiple 2's-11's.

I guess if you move 6 along each time? But then after 6 rows you start repeating.

But OK, fair enough... you're not interested in the algorithm but more in intelligence to find solutions. Well, I guess one thing would be how you approach the search space.

At the moment, your approach seems to be "start with some numbers then guess some more". Perhaps an alternative approach would be to think of it as an ordering. You have 36 1's, 36 2's.... and 36 36's. This is your set of numbers. Lay your set out in some initial order. See if it works, if not, try swapping two set members at random.

That's the initial, brute force solution - pretty stupid and slow. The smarts come in when you decide which numbers to swap.

Gosh, what you are doing sounds like much more fun than the sort of programming I have to do ;-)
