SynchronousIterationStrategy

public SynchronousIterationStrategy()

Method Detail

getClone

public SynchronousIterationStrategy getClone()

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface IterationStrategy<PSO>

Specified by:

getClone in interface Cloneable

Specified by:

getClone in class AbstractIterationStrategy<PSO>

Returns:

An exact clone of the current object instance.

Object.clone()

performIteration

public void performIteration(PSO pso)

This is an ASynchronous strategy:

1. For all particles:
1. Update the particle velocity
2. Update the particle position
2. For all particles:
1. Calculate the particle fitness
2. For all paritcles in the current particle's neighbourhood:
1. Update the nieghbourhooh best

Specified by:

performIteration in interface IterationStrategy<PSO>

Specified by:

performIteration in class AbstractIterationStrategy<PSO>

Parameters:

pso - The PSO to have an iteration applied.
