" This rule states that the ratio of successful mutations to all mutations should be 1/5, hence if the ratio is greater than 1/5 then increase the step size, and if the ratio is less than 1/5 then decrease the step size. "

...upon a success level achieved in the previous "p" generations. The 1/5 success rule (Rechenberg, 1973) states that the ratio of successful mutations to all mutations should be 1/5. If the value of this ratio is higher than 1/5 increase a, otherwise reduce it. The rationale behind...

...Rechenberg's 3- success rule in evolution strategies, which was used to vary the step size of mutation [530]. The rule states that the ratio of successful mutations to all mutations should be j; hence, if the ratio is greater than j, the step size should be increased. and if the ratio is less...

...rule Rechenberg's '1/5 success rule' incorporates feedback from the search process. The 1/5 success rule states that • The ratio of successful mutations to all mutations should be 1/5. • If this ratio is greater than 1/5, then the standard deviation should be increased. • If the...
