Struct SimulatedAnnealingAcceptor 

pub struct SimulatedAnnealingAcceptor { /* private fields */ }

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). Calibrate to ~20% of the initial hard score magnitude for best results.
• decay_rate - Multiplicative decay per step (e.g., 0.9999 for 30s runs at ~10k steps/s gives final T ≈ 0.05 * starting T).

pub fn with_seed(starting_temperature: f64, decay_rate: f64, seed: u64) -> Self

pub fn auto_calibrate(decay_rate: f64) -> Self

Auto-calibrates starting temperature from the initial score.

Sets temperature to 20% of the absolute initial score magnitude, ensuring ~80% acceptance probability for moves with delta = |initial_score|.
