org.uma.evolver.metaoptimizationproblem.evaluationbudgetstrategy.FixedEvaluationsStrategy

All Implemented Interfaces:

EvaluationBudgetStrategy

public class FixedEvaluationsStrategy
extends Object
implements EvaluationBudgetStrategy

Implementation of EvaluationBudgetStrategy that uses fixed evaluation counts for each problem. The number of evaluations is specified explicitly for each problem in the constructor.

Constructor Details

FixedEvaluationsStrategy

public FixedEvaluationsStrategy(List<Integer> evaluations)

Creates a new FixedEvaluationsStrategy with the specified evaluation counts.

Parameters:

evaluations - a list containing the number of evaluations for each problem

Throws:

NullPointerException - if evaluations is null

IllegalArgumentException - if evaluations is empty

Method Details

getEvaluations

public int getEvaluations(int problemIndex)

Description copied from interface: EvaluationBudgetStrategy

Retrieves the number of evaluations to be performed for a specific problem. The implementation should handle the logic for determining the evaluation count, which could be fixed, random, or based on some other criterion.

Specified by:

getEvaluations in interface EvaluationBudgetStrategy

Parameters:

problemIndex - the zero-based index of the problem in the problem list

Returns:

the number of evaluations to perform for the specified problem

validate

public void validate(int numberOfProblems)

Description copied from interface: EvaluationBudgetStrategy

Validates the configuration of the evaluation budget strategy against the number of problems. Implementations should throw an IllegalArgumentException if the configuration is invalid for the given number of problems.

Specified by:

validate in interface EvaluationBudgetStrategy

Parameters:

numberOfProblems - the total number of problems to be evaluated

getEvaluations

public List<Integer> getEvaluations()

Returns an unmodifiable view of the evaluation counts.

Returns:

the list of evaluation counts
