Calling some function before fitness_func in adaptive mutation

[hmcezar]

During the adaptive mutation, the fitness function is called in

GeneticAlgorithmPython/pygad/utils/mutation.py

Line 473 in 0e8be9d

def adaptive_mutation_population_fitness(self, offspring):

In my application, this is a problem because I have to normalize some optimized probabilities before computing the fitness.
So if I have g1, g2, g3, g4 as genes that are optimized with the GA, and I need sum(g1, g2, g3, g4) = 1 for my fitness function, I most likely get an error.

The way I'm doing things with random mutation is that I normalize this in my on_mutation method.
Is there a way of using adaptive mutation with such restrictions?
