Functions

func PointMutation

func PointMutation(pset tree.PrimitiveSet) engine.MutationFunc[tree.Tree]

PointMutation returns a mutation function that randomly changes the function or terminal value of a node.

func SubtreeCrossover

func SubtreeCrossover() engine.CrossoverFunc[tree.Tree]

SubtreeCrossover returns a crossover function for GP trees. It selects a random node in both parents and swaps the subtrees rooted at those nodes.

func SubtreeMutation

func SubtreeMutation(maxDepth int, pset tree.PrimitiveSet) engine.MutationFunc[tree.Tree]

SubtreeMutation returns a mutation function that replaces a random node with a newly generated subtree.
