xegaGpMutateAllGene: Mutate a gene.

In xegaGpGene: Genetic Operations for Grammar-Based Genetic Programming

Mutate a gene.

Description

xegaGpMutateAllGene() replaces a randomly selected subtree by a random derivation tree with the same root symbol with a small probability. All non-terminal nodes are considered as insertion points. Depth-bounds are respected.

Usage

xegaGpMutateAllGene(g, lF)

Arguments

g	Derivation tree.
lF	Local configuration of the genetic algorithm.

Details

Mutation is controlled by one local parameter:

1. lF$MaxMutDepth() controls the maximal depth of the new random generation tree.

This version of the genetic operator skips the filter loop.

Value

Derivation tree.
