looking into speeding up the GA code I posted, I ran it with cProfile.

Fri Feb 01 11:05:57 2008    evprof

         30100116 function calls in 93.614 CPU seconds

   Ordered by: internal time

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)

objects}

'_random.Random' objects}
    80380    2.659    0.000    4.592    0.000
quickga.py:15(rationalise_signs)

... Does this in essence mean the main place I should be looking is mutate()
I'm imagining randint and randrange are already as fast as they can be..
