Considering duplicates across populations

[Leviathan321]

I am wondering whether there is a mechanism in pymoo to consider duplicates across populations to reduce the evaluation time? I am using the famework for an application where evaluations are expensive simulations. And I get a lot of duplicates sometimes.

I have only encountered so far dupliate elemination for the offspring generation. Is there such a mechanism across populations? Or can maybe someone sketch an appropriate place where this could be integrated?
