Struct HillClimbingAcceptor 

pub struct HillClimbingAcceptor;

Hill climbing acceptor - accepts only improving moves.

This is the simplest acceptor. It only accepts moves that result in a strictly better score. This can get stuck in local optima.

Example

use solverforge_solver::phase::localsearch::HillClimbingAcceptor;

let acceptor = HillClimbingAcceptor::new();

Implementations

impl HillClimbingAcceptor

pub fn new() -> Self

Creates a new hill climbing acceptor.
