Package ec

Class ec.Breeder extends java.lang.Object implements Serializable

Class ec.BreedingPipeline extends BreedingSource implements Serializable

Serialized Fields

mybase

Parameter mybase

sources

BreedingSource[] sources
Array of sources feeding the pipeline

Class ec.BreedingSource extends java.lang.Object implements Serializable

Serialized Fields

probability

float probability
The probability that this BreedingSource will be chosen to breed over other BreedingSources. This may or may not be used, depending on what the caller to this BreedingSource is. It also might be modified by external sources owning this object, for their own purposes. A BreedingSource should not use it for any purpose of its own, nor modify it except when setting it up.

The most common modification is to normalize it with some other set of probabilities, then set all of them up in increasing summation; this allows the use of the fast static BreedingSource-picking utility method, BreedingSource.pickRandom(...). In order to use this method, for example, if four breeding source probabilities are {0.3, 0.2, 0.1, 0.4}, then they should get normalized and summed by the outside owners as: {0.3, 0.5, 0.6, 1.0}.

Class ec.EvolutionState extends java.lang.Object implements Serializable

serialVersionUID: -1L

Serialized Fields

parameters

IParameterDatabase parameters
The parameter database (threadsafe). Parameter objects are also threadsafe. Nonetheless, you should generally try to treat this database as read-only.

random

MersenneTwisterFast[] random
An array of random number generators, indexed by the thread number you were given (or, if you're not in a multithreaded area, use 0). These generators are not threadsafe in and of themselves, but if you only use the random number generator assigned to your thread, as was intended, then you get random numbers in a threadsafe way. These generators must each have a different seed, of course.v

output

IOutput output
The output and logging facility (threadsafe). Keep in mind that output in Java is expensive.

breedthreads

int breedthreads
The requested number of threads to be used in breeding, excepting perhaps a "parent" thread which gathers the other threads. If breedthreads = 1, then the system should not be multithreaded during breeding. Don't modify this during a run.

evalthreads

int evalthreads
The requested number of threads to be used in evaluation, excepting perhaps a "parent" thread which gathers the other threads. If evalthreads = 1, then the system should not be multithreaded during evaluation. Don't modify this during a run.

checkpoint

boolean checkpoint
Should we checkpoint at all?

checkpointPrefix

java.lang.String checkpointPrefix
The requested prefix start filenames, not including a following period. You probably shouldn't modify this during a run.

checkpointModulo

int checkpointModulo
The requested number of generations that should pass before we write out a checkpoint file.

randomSeedOffset

int randomSeedOffset
An amount to add to each random number generator seed to "offset" it -- often this is simply the job number. If you are using more random number generators internally than the ones initially created for you in the EvolutionState, you might want to create them with the seed value of seedParameter+randomSeedOffset. At present the only such class creating additional generators is ec.eval.MasterProblem.

quitOnRunComplete

boolean quitOnRunComplete
Whether or not the system should prematurely quit when Evaluator returns true for runComplete(...) (that is, when the system found an ideal individual.

job

java.lang.Object[] job
Current job iteration variables, set by Evolve. The default version simply sets this to a single Object[1] containing the current job iteration number as an Integer (for a single job, it's 0). You probably should not modify this inside an evolutionary run.

runtimeArguments

java.lang.String[] runtimeArguments
The original runtime arguments passed to the Java process. You probably should not modify this inside an evolutionary run.

generation

int generation
The current generation of the population in the run. For non-generational approaches, this probably should represent some kind of incrementing value, perhaps the number of individuals evaluated so far. You probably shouldn't modify this.

numGenerations

int numGenerations
The number of generations the evolutionary computation system will run until it ends. If after the population has been evaluated the Evaluator returns true for runComplete(...), and quitOnRunComplete is true, then the system will quit. You probably shouldn't modify this.

population

Population population
The current population. This is not a singleton object, and may be replaced after every generation in a generational approach. You should only access this in a read-only fashion.

initializer

Initializer initializer
The population initializer, a singleton object. You should only access this in a read-only fashion.

finisher

Finisher finisher
The population finisher, a singleton object. You should only access this in a read-only fashion.

breeder

Breeder breeder
The population breeder, a singleton object. You should only access this in a read-only fashion.

evaluator

Evaluator evaluator
The population evaluator, a singleton object. You should only access this in a read-only fashion.

statistics

Statistics statistics
The population statistics, a singleton object. You should generally only access this in a read-only fashion.

exchanger

Exchanger exchanger
The population exchanger, a singleton object. You should only access this in a read-only fashion.

context_

StateExecutionContext context_
Used for Frontier remote task execution context.

parent

GPNodeParent parent
The GPNode's parent. 4 bytes. :-( But it really helps simplify breeding.

children

GPNode[] children

argposition

byte argposition
The argument position of the child in its parent. This is a byte to save space (GPNode is the critical object space-wise) -- besides, how often do you have 256 children? You can change this to a short or int easily if you absolutely need to. It's possible to eliminate even this and have the child find itself in its parent, but that's an O(children[]) operation, and probably not inlinable, so I figure a byte is okay.

constraints

byte constraints
The GPNode's constraints. This is a byte to save space -- how often do you have 256 different GPNodeConstraints? Well, I guess it's not infeasible. You can increase4 this to an int without much trouble. You typically shouldn't access the constraints through this variable -- use the constraints(state) method instead.
