Mutation types in EvolutionaryParamterOptimization

Hi,

how does "switching mutation" and "sparsity_mutation" work as mutation_types in the EvolutionaryParamterOptimization?
Do you have any reference for that? I couldn't find anything in the manual.

Thank you in advance.

Ben

    Hi,
    both types mutate each value with 1/population size. If you use switching mutation, each mutated value changes from min to max or from max to min.
    Sparsity_mutation causes the mutated value to change from min to a random number between min and max or from any value unequal min to min.
