Struct ScoreCalculationCountTermination 

pub struct ScoreCalculationCountTermination<S: PlanningSolution> { /* private fields */ }

Terminates when a maximum number of score calculations is reached.

This termination condition requires a StatisticsCollector to be attached to the SolverScope. If no collector is attached, it will never terminate.

Example

use solverforge_solver::termination::ScoreCalculationCountTermination;
use solverforge_core::score::SimpleScore;
use solverforge_core::domain::PlanningSolution;

#[derive(Clone)]
struct MySolution;
impl PlanningSolution for MySolution {
    type Score = SimpleScore;
    fn score(&self) -> Option<Self::Score> { None }
    fn set_score(&mut self, _: Option<Self::Score>) {}
}

// Terminate after 10,000 score calculations
let termination = ScoreCalculationCountTermination::<MySolution>::new(10_000);

Implementations

impl<S: PlanningSolution> ScoreCalculationCountTermination<S>

pub fn new(score_calculation_count_limit: u64) -> Self

Arguments

• score_calculation_count_limit - Maximum score calculations before terminating
