Questions: How can I access the active population of current generation? / How can I ensure nonrepetitive individuals among the population?

Hi!

I wrote my own diversity measure to be executed on every generation. I’m using the peek method to invoke my method so I can access the population via result.getPopulation() method. But by assessing the population i’ve noticed that population size increases during each evolution step. I tried to filter the population by generation and isValid method, but it didn’t seem to be correct because i’m getting a population greater than my population size parameter and there are duplicated individuals inside of it. So, here comes my questions:

How can I access the active population of current generation? How can I ensure nonrepetitive individuals among the population?

Accessing population final Population<IntegerGene, Double> population = result.getPopulation();

This is my genotype: Factory<Genotype<IntegerGene>> gtf = Genotype.of(IntegerChromosome.of(1, 5, (int) chromosomeSize));

=== Thank you for the library, by the way!

Good, I think #234 caused the problem.

Was using 3.8! Thought it was 3.9, sorry. Running on 3.9 everything went fine! Thanks!
