Repeated individuals in Pareto Front #442

Open palatos opened 4 years ago

palatos commented 4 years ago

I am using DEAP for a multi-objective problem and I've been noticing the Pareto Front contains repeated individuals.

Is this expected behavior? I remember reading the default similarity check for ParetoFront() is operator.eq, so it shouldn't be allowing identical individuals, right?

I'm using:

hof = tools.ParetoFront()

To define it.

Thanks in advance for any help!
