The modifications to pygad are annotated as "#barloff" for easy search. This modifications (1) allow to pass the user's Class instance reference for persistence flow of computations; (2) this Class instance reference is now declared in the on_ GA call implementations, set to None as default at the user side, and (3) specifically for on_crossover and on_mutation references now are always executed, even when crossover_type and mutation_type are None.

The modifications to pygad are annotated as "#barloff" for easy search. The modifications:
(1) Allow to pass the user's Class instance reference for persistence flow of computations
(2) The user Class instance reference is now an optional parameter (cls_inst) provisioned to GA class constructor
(3) The on_crossover and on_mutation references now are always executed, even when crossover_type and mutation_type are None.
Now, when the fitness function or a on_ (e.g., on_parents) callback is made, the user is passed a reference to its own class instance. The implementation has access to its own attributes from within the callbacks.
