Example of a Boltzmann Selection Function

[chadb56]

Can you provide me with an example of how to implement a selection function that selects the parents from a Boltzmann distribution? I was reading this article in which they use a Boltzmann selection method, and I would like to replicate their results using PyGad, but I'm not sure how to properly implement.

There is no example yet about selecting parents using Boltzmann distribution.

But you can create a custom parent selection function/method and assign it to the parent_selection_type parameter. This is a dummy example:
