Scales mutation across range of parameter
Alias: none
Argument(s): REAL
Default: 0.15
The mutation_scale is a fraction in the range [0, 1] and is meant to help control the amount of variation that takes place when a variable is mutated. Its behavior depends on the selected mutation_type
. For offset_normal
and offset_cauchy
, mutation_scale
is multipled by the range of the variable being mutated to obtain the standard deviation of the offset. For offset_uniform
, the range of possible deviation amounts is +/- 1/2 * (mutation_scale * variable range).
