Struct DEConfigBuilder 

pub struct DEConfigBuilder { /* private fields */ }

Fluent builder for DEConfig for ergonomic configuration.

Example

use autoeq_de::{DEConfigBuilder, Strategy, Mutation};

let config = DEConfigBuilder::new()
    .maxiter(500)
    .popsize(20)
    .strategy(Strategy::Best1Bin)
    .mutation(Mutation::Factor(0.8))
    .recombination(0.9)
    .seed(42)
    .build();
