I think you should wallow in their glory of this is being done in hardware. Less than one second to solve the 'hardest' puzzle with one solution is very impressive. I assume some bits are done using support CPU - (I heard 'C' bitmaps being mentioned for drawing the digits). I wish they had implemented a C version of the backtracker and did some comparisons. In the words of their professor, 'Awesome!'.
Asking about the worst case scenario really stumped them, and anyone who had not looked into the math before hand! Great project. :)
Cool!
Actually Sudoku puzzles should only have one valid solved state. A Sudoku puzzle with more than one valid final states is considered to be flawed.
