It's interesting to look at the rate of growth for the win and failure trees:
n wins fails 0 1 0 1 1 0 2 2 0 3 5 1 4 16 8 5 62 58 6 286 434 7 1519 3521 8 9184 31136 Simple cases are more predictable. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
