Specific hypermutation operators are one of the distinguishing features of artificial immune systems. They can be considered in isolation and compared with other variation operators. For a specific immune-inspired hypermutation operator, hypermutations with inversely proportional mutation potential, an analysis of its ability to locate optima precisely and in large distance from other promising regions of the search space is presented. Four different specific variants of this mutation operator are considered. Two of these turn out to be very inefficient in locating optima precisely while the other two are able to do this efficiently. Based on these findings an improved version of this kind of mutation is introduced that removes some of the deficiencies and allows to parameterize the trade-off between efficiency in local search and the ability to perform huge changes in single mutations.
