Evaluator

class Evaluator @JvmOverloads constructor(val problemDefinition: ProblemDefinition, simulator: SimulationOracleIfc, val cache: SolutionCacheIfc? = null) : EvaluatorIfc(source)

An evaluator should communicate with the simulation oracle to determine solutions for requests for evaluation from solvers.

Parameters

problemDefinition

the problem that the evaluation of responses will be used on

simulator

the provider of responses from the simulation oracle

cache

a cache that can be used instead of a costly simulation evaluation

Constructors

constructor(problemDefinition: ProblemDefinition, simulator: SimulationOracleIfc, cache: SolutionCacheIfc? = null)

Types

object Companion

Properties

open override val cache: SolutionCacheIfc? = null

problemDefinition

val problemDefinition: ProblemDefinition

totalCachedEvaluations

var totalCachedEvaluations: Int

The total number of evaluations performed via the cache.

totalCachedReplications

var totalCachedReplications: Int

The total number of replications satisfied by the cache.

totalEvaluations

var totalEvaluations: Int

The total number of evaluations performed. An evaluation may have many replications.

totalOracleEvaluations

var totalOracleEvaluations: Int

The total number of evaluations performed via the simulation oracle.

totalOracleReplications

var totalOracleReplications: Int

The total number of replications performed by the simulation oracle.

totalReplications

val totalReplications: Int

The total number of replications requested across all evaluation requests.

totalRequestsReceived

var totalRequestsReceived: Int

The total number of evaluation requests that were received.

Functions

open override fun evaluate(evaluationRequest: EvaluationRequest): Map<ModelInputs, Solution>

Processes the supplied requests for solutions. The solutions may come from an associated solution cache (if present or allowed) or via evaluations by the simulation oracle. The CRN option is applied to the set of requests and does not permit cached solutions, even if caching is permitted.

resetEvaluationCounts

fun resetEvaluationCounts()

The evaluator collects some basic counts (statistics) on its evaluations. This function resets all counters to 0, perhaps in preparation for another evaluation run.
