score_best: f64

Score for finding new best solution

score_better: f64

Score for finding better solution than current

score_accepted: f64

Score for accepting worse solution

reaction_factor: f64

Reaction factor (how quickly weights adapt, 0-1)

min_weight: f64

Minimum operator weight

initial_temperature: f64

Initial temperature for SA acceptance

cooling_rate: f64

Cooling rate for SA acceptance (0-1)

final_temperature: f64

Final temperature threshold

seed: Option<u64>

Random seed for reproducibility (None = random)
