- Type Parameters:
T- The type of object used to represent candidate solutions to the problem.
A HybridCrossover enables using multiple crossover operators for the evolutionary algorithm, such that each time the
cross(T, T)method is called, a randomly chosen crossover operator is applied to the candidate solution. The random choice of crossover operator is approximately uniform from among the available crossover operators.
Method SummaryModifier and TypeMethodDescription
voidPerforms a crossover for an evolutionary algorithm, such that crossover forms two children from two parents.
split()Generates a functionally identical copy of this object, for use in multithreaded implementations of search algorithms.
HybridCrossoverConstructs a HybridCrossover from a Collection of CrossoverOperator.
crossoverOps- A Collection of CrossoverOperator.
IllegalArgumentException- if crossoverOps doesn't contain any CrossoverOperators.
crossDescription copied from interface:
CrossoverOperatorPerforms a crossover for an evolutionary algorithm, such that crossover forms two children from two parents. Implementations of this method modify the parameters, transforming the parents into the children.
splitDescription copied from interface:
SplittableGenerates a functionally identical copy of this object, for use in multithreaded implementations of search algorithms. The state of the object that is returned may or may not be identical to that of the original. Thus, this is a distinct concept from the functionality of the
Copyableinterface. Classes that implement this interface must ensure that the object returned performs the same functionality, and that it does not share any state data that would be either unsafe or inefficient for concurrent access by multiple threads. The split method is allowed to simply return the this reference, provided that it is both safe and efficient for multiple threads to share a single copy of the Splittable object. The intention is to provide a multithreaded search with the capability to provide spawned threads with their own distinct search operators. Such multithreaded algorithms can call the split method for each thread it spawns to generate a functionally identical copy of the operator, but with independent state.
