[Icfp04-discuss] simulator speed

[Jeff Franklin]

Hi all,

Sorry to waste everyones time on this, but I figured out what the problem was.  
I added some dynamic programming to the random number generator so it 
wouldn't have to recurse as much, and it's running much faster now: 22seconds 
for what was taking 22 minutes for 10000 iterations and I can do a full 
simulation in about 4 minutes.

Thanks to all,
-Jeff
