xegaPermMutateGenekInversion: Mutate a gene (k random inversions).

In xegaPermGene: Operations on Permutation Genes

Mutate a gene (k random inversions).

Description

xegaPermMutateGenekInversion performs k random inversions. The number of inversions is exponentially decaying with exponential decay constant lambda.

Usage

xegaPermMutateGenekInversion(gene, lF)

Arguments

gene	A Permutation.
lF	Local configuration of the genetic algorithm.

Details

The only difference to the order-based mutation operator (Syswerda, 1991) is the exponential decay in the number of inversions.

1. The indices of a random subschedule are extracted.

2. The subschedule is extracted, permuted, and reinserted.

Value

A Permutation.
