# mutation_scale

Scales mutation across range of parameter

Specification

- Alias: None

- Arguments: REAL

- Default: 0.15

Description

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).
