without                 Returns elements of vector 'x' without elements
                        in 'y'.

xegaPermCrossGene       Position-based crossover of 2 genes.
xegaPermCrossoverFactory
                        Configure the crossover function of a genetic
                        algorithm.
xegaPermDecodeGene      Decode a permutation.
xegaPermGene            Package xegaPermGene.
xegaPermInitGene        Initialize a gene with a permutation of
                        integers
xegaPermMutateGene2Opt
                        Mutate a gene (by a random 2-Opt move).
xegaPermMutateGeneBestGreedy
                        Mutate a gene (by inserting the best greedy
                        path at a random start position with a random
                        length of k).
xegaPermMutateGeneGreedy
                        Mutate a gene (by inserting a greedy path at a
                        random start position with a random length of
                        k).
xegaPermMutateGeneOrderBased
                        Mutate a gene (generalized order based
                        mutation).
xegaPermMutateGenekInversion
                        Mutate a gene (k random inversions).
xegaPermMutateGenekOptLK
                        Mutate a gene (by a random Lin-Kernighan k-OPT
                        move).
xegaPermMutateMix       Mutation by a random mutation function.
xegaPermMutationFactory
                        Configure the mutation function of a genetic
                        algorithm.
