Cannot Recreate the famous 7 Roach Rush

[GoogleCodeExporter]

What steps will reproduce the problem?
1. input parameters for 7 roaches with all other parameters set to default

What is the expected output? What do you see instead?
I would expect after maybe an hour of running the program that the results of 
the "7 Roach Rush" would be reproduced, but the best results I had were 7 
roaches at 4:55 instead of 4:40.

What version of the product are you using? On what operating system?
Version 23, Windows 7 64 bit

Please provide any additional information below.
I was able to reproduce this in version 22, so I'm not sure if anything changed 
or if this is just the wonder of genetic algorithms.

FYI, here is the build I had this last time. This was after 77+ million games 
played.

It's possible that the algorithm was inadvertently tweaked with all the changes 
that were made since then.  It will also usually produce slightly different 
results every time it is run.

It's funny. Although 7 roaches at 4:40 would certainly be faster, I find this 
build more optimal because you have almost twice the drones you would have with 
the 4:40 build for just a 15 second delay. Plu the first 3 roaches are out 
before 4:40 so you could begin pushing with those and pull back defensively if 
your opponent is well able to defend. Roaches not easily killed, but easily 
chased down. This build also affords you the opportunity to send your drone to 
expand just as the seventh roach arrives providing good defense for your 
expansion. Just my thoughts.

You never know what you're going to get.  That's what makes Evolution Chamber 
such a useful tool for SC2 players.

this doesn't look like an issue, more of a feature. you do end up in a better 
place than with the 7 roach rush. it seems to have built a better mousetrap.
