Methods

impl Solver

pub fn new(
    selection: Box<dyn Selection>,
    mutation: Box<dyn Mutation>,
    acceptance: Box<dyn Acceptance>,
    termination: Box<dyn Termination>,
    quota: Option<Box<dyn Quota + Sync + Send>>,
    initial: Option<InsertionContext>,
    logger: Box<dyn Fn(String)>
) -> Self

Creates a new instance of Solver.

pub fn solve(
    &mut self,
    problem: Arc<Problem>
) -> Option<(Solution, Box<dyn ObjectiveCost + Send + Sync>, usize)>

Solves given problem and returns solution, its cost and generation when it is found. Return None if no solution found.

Trait Implementations

impl Default for Solver

fn default() -> Self

Returns the "default value" for a type.
