I'm trying to figure out how to use ec.coevolve.CompetitiveEvaluator.
I looked at the included coevolve1 problem. Running it, produces a
stat file with some strange results. The end of it says:

Generation: 99
Best Individual:
Evaluated: T
Fitness: 5.0
 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

Best Individual of Run:
Evaluated: T
Fitness: 5.0
 1 0 0 0 1 1 1 0 1 1 1 1 0 0 1 1 0 1 1 1 0 0 1 1 0 1 1 0 1 0 1 0 1 1 1
1 0 1 1 0 0 0 1 1 1 1 0 0 1 1


This makes no sense to me. The best individual of the last generation
is better than the best individual of the run (has more 1s), but has
the same fitness. What gives?
