Expand description

Trait for collecting and selecting moves in local search.

Foragers are responsible for:

  • Collecting accepted move indices during move evaluation
  • Deciding when to quit evaluating early
  • Selecting the best move index to apply

§Type Parameters

  • S - The planning solution type
  • M - The move type (for trait bounds only, moves are never stored)

Required Methods§

Source

fn step_started( &mut self, best_score: S::Score, last_step_score: S::Score, step_seed: u64, )

Source

fn add_move_index( &mut self, index: CandidateId, score: S::Score, ) -> ForagerDecision

Source

fn is_quit_early(&self) -> bool

Source

fn pick_move_index(&mut self) -> Option<(CandidateId, S::Score)>

Provided Methods§

Source

fn accepted_count_limit(&self) -> Option<usize>

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
