Expand description

Tunable inputs for De::new. Non-positive values select DE defaults.

Fields§

§popsize: i32

Population size; non-positive values select the dimension-dependent default.

§max_evaluations: u64

Maximum number of objective evaluations.

§keep: f64

Expected lifetime controlling age-based population reinitialization.

§stop_fitness: f64

Stop after finding an objective value strictly below this threshold.

§f: f64

Base differential weight F.

§cr: f64

Base crossover probability CR.

§min_mutate: f64

Minimum probability used by mixed-integer mutation.

§max_mutate: f64

Maximum probability used by mixed-integer mutation.

§min_sigma: f64

Lower limit for normal-sampling step sizes.

§seed: u64

Seed for the optimizer’s independent random stream.

§runid: i64

Additional run identifier mixed into seed.
