bit_random


Mutate by flipping a random bit

Specification

Alias: none

Argument(s): none

Description

The bit_random mutator introduces random variation by first converting a randomly chosen variable of a randomly chosen design into a binary string. It then flips a randomly chosen bit in the string from a 1 to a 0 or visa versa. In this mutation scheme, the resulting value has more probability of being similar to the original value.
