  com.epochx.core.GPRun<TYPE>

public class GPRun<TYPE>
extends java.lang.Object

A GPRun object has 2 responsibilities. Firstly, to execute a GP run based upon the control parameters provided. Secondly, after executing to provide basic details of how that run went.

Objects of this class should be immutable - however the underlying objects, in particular GPModel may not be.

Method Summary

double	getBestFitness() Retrieve the fitness score of the CandidateProgram returned by getBestProgram().
CandidateProgram<TYPE>	getBestProgram() Retrieve the CandidateProgram with the best fitness found during the run.
long	getRunTime() Retrieve the time in nano-seconds of the run.
static <TYPE> GPRun<TYPE>	run(GPModel<TYPE> model) Construct a new GPRun object and execute it.

Method Detail

run

public static <TYPE> GPRun<TYPE> run(GPModel<TYPE> model)

Construct a new GPRun object and execute it. The GPModel passed in is used to provide the control parameters for the run.

Type Parameters:

TYPE - the type of CandidateProgram to be evolved.

Parameters:

model - the model which will control the run with the parameters and fitness function to use.

Returns:

The GPRun object that was executed, containing retrievable details about the run.

GPModel

getBestProgram

public CandidateProgram<TYPE> getBestProgram()

Retrieve the CandidateProgram with the best fitness found during the run. This CandidateProgram may have been found in any of the generations.

Returns:

the CandidateProgram with the best fitness score found.

getBestFitness

public double getBestFitness()

Retrieve the fitness score of the CandidateProgram returned by getBestProgram(). A lower fitness score is considered better than a higher fitness score.

Returns:

the fitness score of the best CandidateProgram found during execution.

getRunTime

public long getRunTime()

Retrieve the time in nano-seconds of the run. This will be either the length of the whole run if it's finished or the time up until now if the run is not finished.

Returns:

The run time in nano-seconds.
