Operations on Permutation Genes

CRAN Package

An implementation of representation-dependent gene level operations for genetic algorithms with genes which represent permutations: initialization of genes, mutation and crossover. The crossover operation provided is position-based crossover (Syswerda, G., Chap. 21 in Davis, L. (1991, ISBN:0-442-00173-8). For mutation, several variants are included: Order-based mutation (Syswerda, G., Chap. 21 in Davis, L. (1991, ISBN:0-442-00173-8), randomized Lin-Kernighan heuristics doi:10.1287/opre.6.6.791 and Lin, S. and Kernighan. B. W. (1973) doi:10.1287/opre.21.2.498, and randomized greedy operators. A random mix operator for mutation selects a mutation variant randomly.
