Is there any way to know and change the mutation and recombination rate of the differential evolution algorithm in BlackBoxOptim?

It seems you can pass parameters for the method as the second argument of bboptimize (before keyword arguments).

You can see the default parameters here :

Not sure if there’s something like a recombination rate in there.

Great, thank you, this is what I need! :grinning:
