Simply returns state.population.

Called by pipelines before they've modified the individual and it might need to be "fixed" -- basically a hook for you to override. B

Prints the gene to a string in a fashion readable by readGeneFromString and parseable by readGene(state, reader). Override this. The default

Should print the individual in a way that can be read by computer, including its fitness, with a verbosity of Output.V_NO_GENERAL.

Returns true if this BreedingSource, when attached to the given subpopulation, will produce individuals of the subpopulation's species.

TODO Check if the overflow case is really needed

Representation invariant, used for verification. @return true if the class is found to be in an erroneous state.

Initializes the individual by randomly choosing doubles uniformly from mingene to maxgene.

Returns an EvolutionState object read from a checkpoint file whose filename is <i>checkpoint</i> @exception java.lang.ClassNotFoundExc

Returns the root ancestor of this node. O(ln n) average case, O(n) worst case.

Schedules a job for execution on one of the available slaves. The monitor waits until at least one slave is available to perform the job.

Writes the evolution state out to a file.

Copy the values provided so the testing data is available as required. @param vals - the testing values for this terminal symbol

Sets the fitness to be the same value as the mean of the provided fitnesses. The default version of this method exits with an "unimplemented

Copy the values provided so the training data is available as required. @param vals - the training values for this terminal symbol

Returns true if the subpopulation should be evaluated. This will happen if the Breeder believes that the subpopulation should be breed afterw

Shuffles (randomizes the order of) the IntBag

Starts script on the given server. The syntax of <code>scriptName</code> is as follows: <code>filename[!packagename.classname]</code> Here <code>filen

Returns the <i>n</i>th item in the stack (0-indexed), or null if this goes to the bottom of the stack.

An expensive function which determines my tree number -- only use for errors, etc. Returns ec.gp.GPTree.NO_TREENUM if the tree number

This method returns only when all slaves have finished the jobs that they were assigned. While this method waits, new jobs can be assigned to

Calculates the 'raw' fitness for the ACC (Accuracy) type fitness (before the normalization from 0 to max value is done). @param useTrainingData true i

Calculates the 'raw' fitness for the CC (Correlation Coefficient) type fitness (before the normalization from 0 to max value is done). @param useTrain

Calculates the 'raw' fitness for the MAE (Mean Absolute Error) type fitness (before the normalization from 0 to max value is done). @param useTraining

Calculates the fitness for the MSE (Mean Squared Error) type fitness. Gets the raw fitness and then normalizes between 0 and max value as (maxValue (1

Calculates the 'raw' fitness for the RAE (Relative Absolute Error) type fitness (before the normalization from 0 to max value is done). @param useTrai

Calculates the 'raw' fitness for the RMSE (Root Mean Squared Error) type fitness (before the normalization from 0 to max value is done). @param useTra

Calculates the 'raw' fitness for the RRSE (Root Relative Squared Error) type fitness (before the normalization from 0 to max value is done). @param us

Calculates the 'raw' fitness for the RSE (Relative Squared Error) type fitness (before the normalization from 0 to max value is done). @param useTrain

Activates the net such that all outputs are active.

We append new gene(s) to the current genome

Adds the peers defined in <code>cfg</code> to the default peer list of the collective. Initializes peers from the properties starting with "base" or "

Add a parameter node for a function. @param node the parameter node

Adds a peer address to exchange information with. This class needs peer addresses to talk to. The implementation of the collective requires that we kn

A private helper function for breedPopulation which breeds a chunk of individuals in a subpopulation for a given thread. Although this

Use super's breeding, but also set our local state to record that breeding is complete.

Allows MultiObjectiveStatistics etc. to call super.super.finalStatistics(...) without calling super.finalStatistics(...)

Allows MultiObjectiveStatistics etc. to call super.super.postEvaluationStatistics(...) without calling super.postEvaluationStatistics(...)

Check to see if the digits that are going to be truncated because of the precision should force a round in the preceding digits. @param ca1 the array

Begins a fresh evolutionary run with a given state. The state should have been provided by initialize(...). The jobPrefix is added to the fr

Erases the image.

This function gives a measure of compatibility between two Genomes by computing a linear combination of 3 characterizing variables of their compatibil
