The well known problems of packing are all NonPolynomial and are of a great theoretical and practical interest. The record dense packing of 256 equal circles inside a square, obtained by the Pack'n'tile software:
The natural question is, how the Critticall would handle them. Since there is a huge academic and hobbyist tradition for solving this kind of riddles, it was not hard to find some challenges and to do some comparisons how good we really are with this method. It turns out that the Critticall's engine is quite optimal! What was accomplished by many different people with many different algorithms and computer programs through the decades, is quite easily matched and surpassed by a program you may download and try to a degree.
The density of 256 circles arranged inside a square, as you can see at www.packomania.com has been surpassed from scratch in a matter of hours. Now as the task is mechanized, get your own machine at www.algit.eu and contribute to the packing saga, which has just begun. Be an explorer at the packing frontier, have fun and do science yourself!
