Parameters for Lexicon genetic programming (GP).

Fields

n_crosses: usize

The number of hypotheses crossover should generate.

max_sample_depth: usize

The maximum number of non-progressing recursive steps sampling can make without failing.

p_add: f64

The probability of adding (vs. deleting) a rule during mutation.

p_keep: f64

The probability of keeping a rule during crossover.

templates: Vec<RuleContext>

Rule templates to use when sampling rules.

atom_weights: (f64, f64, f64)

The weight to assign variables, constants, and non-constant operators, respectively.
