class geneticengine.representations.grammatical_evolution.structured_ge.StructuredGrammaticalEvolutionRepresentation(grammar, max_depth, gene_length=256, initialization_mode=pi_grow_method)

Bases: geneticengine.representations.api.Representation[Genotype, geneticengine.solutions.tree.TreeNode], geneticengine.representations.api.RepresentationWithMutation[Genotype], geneticengine.representations.api.RepresentationWithCrossover[Genotype]

This version uses a list of lists of integers to represent individuals, based on non-terminal symbols.

Parameters:

grammar (Grammar) – The grammar to use in the mapping
max_depth (int) – the maximum depth when performing the mapping
initialization_mode (InitializationMethodType) – method to create individuals in the mapping (e.g., pi_grow, full, grow)
gene_length (int)
