Struct rosomaxa::TelemetryHeuristicContext

pub struct TelemetryHeuristicContext<O, S>
where
    O: HeuristicObjective<Solution = S>,
    S: HeuristicSolution,
{ /* private fields */ }

A default heuristic context implementation which uses telemetry to track search progression parameters.

Implementations

impl<O, S> TelemetryHeuristicContext<O, S>

where O: HeuristicObjective<Solution = S>, S: HeuristicSolution,

pub fn new( objective: Arc<O>, population: Box<DynHeuristicPopulation<O, S>>, telemetry_mode: TelemetryMode, environment: Arc<Environment> ) -> Self

Creates a new instance of TelemetryHeuristicContext.

pub fn add_solution(&mut self, solution: S)

Adds solution to population.
