The mutation_type
controls what approach is employed in randomly modifying continuous design variables within the EA population. Each of the mutation methods generates coordinate-wise changes to individuals, usually by adding a random variable to a given coordinate value (an offset_*
mutation), but also by replacing a given coordinate value with a random variable (a replace_*
mutation).
Discrete design variables are always mutated using the offset_uniform
method.
