I had a *Really* fun night last night – I never really liked playing Sudoku, but I always had a nagging feeling that there would be some neat way to look at it using convering spaces – I only got around to actually trying that out last night, and I think that I managed to translate the problem of generating solutions into a problem of graph theory (which I can’t solve, but that’s the easy part, right? ;) ), which has brought me a certain amount of satisfaction, because I haven’t done maths in ages.
