In the run described below, it looks like the evolutionary process is
favoring low fitness values, but whatever is keeping track of the
"best individual" prefers high fitnesses. Am I missing something?
(I should note that I'm using a new version of
ec.coevolve.CompetitiveEvaluator that Liviu sent me.)

I modified coevolve1.params to use a random-two-ways tournament:
eval.style = rand-2-ways
eval.group-size = 7
Then I ran:
java ec.Evolve -file ec/app/coevolve1/coevolve1.params
Here's the beginning and end of the resulting out.stat file:
