Uses of Singleton in ec

Classes in ec that implement Singleton

Modifier and Type	Class and Description
class	Breeder A Breeder is a singleton object which is responsible for the breeding process during the course of an evolutionary run.
class	Evaluator An Evaluator is a singleton object which is responsible for the evaluation process during the course of an evolutionary run.
class	EvolutionState An EvolutionState object is a singleton object which holds the entire state of an evolutionary run.
class	Exchanger The Exchanger is a singleton object whose job is to (optionally) perform individual exchanges between subpopulations in the run, or exchange individuals with other concurrent evolutionary run processes, using sockets or whatever.
class	Finisher Finisher is a singleton object which is responsible for cleaning up a population after a run has completed.
class	Initializer The Initializer is a singleton object whose job is to initialize the population at the beginning of the run.
class	Statistics Statistics and its subclasses are Cliques which generate statistics during the run.
