Struct SimulatedAnnealingAcceptor 

pub struct SimulatedAnnealingAcceptor { /* private fields */ }

Simulated annealing acceptor - accepts moves with temperature-based probability.

Starts with high acceptance probability and gradually decreases it, allowing the search to escape local optima early on.

Example

use solverforge_solver::phase::localsearch::SimulatedAnnealingAcceptor;

let acceptor = SimulatedAnnealingAcceptor::new(1.0, 0.99);

Implementations

impl SimulatedAnnealingAcceptor

pub fn new(starting_temperature: f64, decay_rate: f64) -> Self

Creates a new simulated annealing acceptor.

Arguments

• starting_temperature - Initial temperature (higher = more exploration)
• decay_rate - Multiplicative decay per step (e.g., 0.99)

Trait Implementations

impl<S: PlanningSolution> Acceptor<S> for SimulatedAnnealingAcceptor

fn is_accepted(&self, last_step_score: &S::Score, move_score: &S::Score) -> bool

Returns true if a move resulting in move_score should be accepted, given the previous step’s score.

fn phase_started(&mut self, _initial_score: &S::Score)

Called when a phase starts.

fn step_ended(&mut self, _step_score: &S::Score)

Called when a step ends with an accepted move.

fn phase_ended(&mut self)

Called when a phase ends.

fn step_started(&mut self)

Called when a step starts.

impl Clone for SimulatedAnnealingAcceptor

fn clone(&self) -> SimulatedAnnealingAcceptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SimulatedAnnealingAcceptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SimulatedAnnealingAcceptor

fn default() -> Self

Returns the “default value” for a type.
