Tunable inputs for Pgpe::new.

Fields§

§popsize: i32

Population size; the implementation rounds odd values up for mirrored pairs.

§max_evaluations: u64

Maximum number of objective evaluations.

§stop_fitness: f64

Stop after finding an objective value strictly below this threshold.

§lr_decay_steps: i32

Number of updates over which the center learning rate decays.

§use_ranking: bool

Use rank-normalized utilities instead of raw objective differences.

§center_learning_rate: f64

Initial Adam learning rate for the distribution center.

§stdev_learning_rate: f64

Learning rate for the coordinate-wise standard deviations.

§stdev_max_change: f64

Maximum relative standard-deviation change per update.

§b1: f64

Adam first-moment decay coefficient.

§b2: f64

Adam second-moment decay coefficient.

§eps: f64

Adam numerical-stability constant.

§decay_coef: f64

Multiplicative learning-rate decay coefficient.

§seed: u64

Seed for the optimizer’s independent random stream.

§runid: i64

Additional run identifier mixed into seed.
