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

Class ec.BreedingPipeline extends BreedingSource implements Serializable

Serialized Fields

mybase

Parameter mybase

My parameter base -- I keep it around so I can print some messages that are useful with it (not deep cloned)

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.Evaluator extends java.lang.Object implements Serializable

Serialized Fields

p_problem

Problem p_problem

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

Serialized Fields

statics

java.util.Vector statics

A place for you to stash pointers to static objects so that they'll get serialized. Java doesn't serialize static objects by default; you have to write them yourself. ECJ does this for its Clique objects (for example, GPType or GPNodeConstraints). However, some of these objects (like GPNodeConstraints) are typically only pointed to by bytes, not pointers. This means that if they're all stored in a static hash table, they never get serialized. So we stash one of them here, in statics, and it gets serialized, and is responsible for serializing the rest of 'em.

parameters

ParameterDatabase 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

Output 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.

gc

boolean gc

Whether or not the system should be doing forced garbage collection after each generation. You probably shouldn't modify this during a run.

gcModulo

int gcModulo

The requested number of generations that should pass before we force a garbage collection. For this to have any effect, gc must be true.

aggressivegc

boolean aggressivegc

Whether or not the system should be doing aggressive forced garbage collection after each generation. "Aggressive" means that garbage collection is repeatedly performed until there is absolutely no memory left to reclaim. This flag has no effect unless gc is also set to true. You probably shouldn't modify this during a run.

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.

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

evaluator

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() method instead.
