Access to all non dominated design variable values

[m-balesdent]

Hello,

Thank you very much for this very useful implementation of multi-objective cma-es.

I would like to know if there is a way to have access to the optimization variable values (phenotypes) relative to all the non-dominated objective function values?

I succeeded to get the optimization variable values linked to the kernel incumbents but not for the non dominated solutions.

Thanks !

Mathieu

If you pass the archive option as true, the archive attribute will contain the archive of nondominated values. I am not sure of how to find the respective solutions though. It's probably an oversight that these are not stored.

Out of my head, I would write a small wrapper around the objective function using moarchiving.BiobjectiveNondominatedSortedList to achieve this by using the info parameter of the add method to store the solutions.

The archive option should easily allow to also store all nondominated solutions, not only their f-values.
