Class EvaluateGenData

java.lang.Object

org.licas.ai_solver.eval.EvaluateGenData

Direct Known Subclasses:

Chromosome

public class EvaluateGenData
extends java.lang.Object

This is the base class for evaluating problem data, more specifically using the genetic algorithms classes, but can be used for other types as well. This would typically be done by comparing input data with this object's seed, or evalSeed object. This evaluator also stores the evaluation function that is used to compare its seed object with the problem dataset dataObject.

Field Detail

name

protected java.lang.String name

The evaluator name or id

evalFunction

protected org.ai_heuristic.functs.Function evalFunction

Function used to do the evaluation

evalSeed

protected org.ai_heuristic.eval.metric.MetricDataset evalSeed

The seed that this evaluator uses for comparing problem datasets. This corresponds to the value set that defines the objective value. This could be a single object or a list of objects, but it must be stored in a MetricDataset object. A single value is a list of length 1.

Constructor Detail

EvaluateGenData

public EvaluateGenData(java.lang.String thisName,
                       org.ai_heuristic.eval.metric.MetricDataset thisEvalSeed,
                       org.ai_heuristic.functs.Function thisEvalFunction)

Create a new instance of EvaluateData.

Parameters:

thisName - a name for the evaluator.

thisEvalSeed - the object to seed the evaluation with.

thisEvalFunction - the evaluation function. Can be set later instead.

Method Detail

evaluate

public org.ai_heuristic.eval.metric.ReplySet evaluate(org.ai_heuristic.eval.metric.MetricDataset dataset)
                                               throws java.lang.Exception

Evaluate the problem dataset and return the result.

Parameters:

dataset - to evaluate. Can also be of type MetricCompare, but might then behave differently, depending on the evaluation function.

Returns:

the result of this evaluation.

Throws:

java.lang.Exception - any error.

getName

public java.lang.String getName()

Get the evaluator id or name.

Returns:

the value of name.

getEvalSeed

public org.ai_heuristic.eval.metric.MetricDataset getEvalSeed()

Get the object that seeded this evaluator.

Returns:

the value of evalSeed.

setEvaluationFunction

public void setEvaluationFunction(org.ai_heuristic.functs.Function thisEval)

Set the function used to evaluate the problem data.

Parameters:

thisEval - the evaluation function.
