#2> Note -- this is much slower than the python version
Surprising. Swift, a compiled, static language, is slower than python in this use case?

stuff like this can't help
var n = Double(arc4random_uniform(UInt32(weightTotal * 1000000.0))) / 1000000.0

This is just speculation, but slowness might be because this is being run as a script via /usr/bin/swift, rather than being precompiled into a binary.
Certainly I have found my own Swift scripts seem to be a lot slower than compiled programs.
EDIT: from my own test with 1000 iterations, script version 17s, compiled version (release build) 5.4s

Yep totally, going to take another pass to try and make it faster. This was just a make it work experiment. Had a few fun troubles with random, but at the moment it just crawls :(.

ah great point. I'll time it both ways and see where I'm at.

good stuff. tbh though, only ~3x slowdown in scripting imo is pretty damn good 8)

#8> let POP_SIZE = 50
c'mon everyone knows genetic population is 30
(I kid I kid but that number has an interesting story https://statswithcats.wordpress.com/2010/07/11/30-samples-st... )

#10Are we all just sharing everything we write on here now? Is this notable for some reason?
