refactor(lib): implement generic evolutionary strategy using .wrapped_mut
Thanks to wrapped_mut now the one_to_five strategy can be implemented
without relying on BoundedPerturbation etc.
feat: add possibility to evolve strategy during evolution_algorithm
refactor: generalize apply_to_mutations
refactor(lib): allow modifying mutation perturbation
refactor(lib): add methods to get wrapped perturbations instead of traits.
Remove WrapperPerturbation and ListWrapperPerturbation in favor of
wrapped and wrapped_mut functions on PerturbationOperator. This
allows for easier handling as it's not easy to downcast Any into
WrapperPerturbation or ListWrapperPerturbation. So instead
always return dyn PerturbationOperator instead of dyn Any.
Use dyn Any only for downstasting to concrete types.
This finally allows for apply_to_mutations to be implemented
under MutationPerturbation, allowing to modify the arguments.
chore: do not clone for no reason in local search
feat: add into_iter for population
feat: add utilities to perturbation to iterate through wrappers easily
Make PerturbationOperator implement Any, allowing it to be downcasted.
Make WrapperPerturbation for perturbations that wrap other
perturbations, such as the mutation perturbation and bounded perturbation.
Make ListWrapperPerturbation for pertrubations that wrap multiple
pertrubations, such as the combined perturbation.
This should allow for easily looking through perturbations, finding
all perturbations of a specific type and modifying them. One use
case can be for changing the probability of a mutation perturbation
during evolution.
chore: do not pass pairing as mut
tests: tweak one_max parameters
refactor: abstract pairing to n-ary
tests: adjust evolution one_max algorithm to always find optimum
feat(binary_string): add single bit perturbation, flip perturbation
refactor: pass rng as argument
Instead of having the Rng stored
inside the structs, pass it through
the functions. This means it's no longer
necessary to pass perturbations etc. as mutable.
tests: add simple test for evolution on one_max
refactor: do perturbation in place instead of cloning
fix: tournament selection in case last wins returned wrong index
fix: tournament replacement strategy could be using wrong indices
feat: add best replacement
