What's New - August 2004
27, 2004: Another version of the Knight's Tour program, Knight's
Tour with Constraints, was posted today. It allows users
to add arbitrary constraints specifying one or more (move
number, column, row) constraints for any auto-solve solution
found. The original problem Ian had
was from a programming challenge posted at another
site. He wondered if I could help. So did I, and
when we finally got it working, I decided to generalize the code
and post it, just in case anyone else would be
August 9, 2004:
A stick is broken randomly into 3 pieces. What is the probability that the pieces can be assembled into a triangle?
Random Triangles answers the question empirically. Perhaps the answer is not what one would think!

Viewer Dahlia found a bug in our Crossword Generator program. Non-square boards were filled only to the limit of the smaller dimension. It's fixed today. Thanks, Dahlia for "bugging" me until I took the time from Mr. Kirkman to fix it.
Viewer Charles Doumar sent me a version of the Kirkman 15 Schoolgirls program that finds solutions much faster than mine. I added my "uniqueness checking" code to it and it finds the first 6 unique solutions in pretty quickly. The 7th, and final, unique solution is still hiding after several thousand solutions checked. (Or else we have a bug -surely that couldn't be!)
