Method Detail

getClone

public QuantumPositionUpdateStrategy getClone()

Description copied from interface: PositionUpdateStrategy

Clone the stategy by creating a new object with the same contents and values as the current object.

Specified by:

getClone in interface PositionUpdateStrategy

Specified by:

getClone in interface Cloneable

Returns:

A clone of the current PositionUpdateStrategy

Object.clone()

updatePosition

public void updatePosition(Particle particle)

Update particle position; do it in a standard way if the particle is neutral, and in a quantum way if the particle is charged. The "quantum" way entails sampling the position from a uniform distribution : a spherical cloud around gbest with a radius r.

Specified by:

updatePosition in interface PositionUpdateStrategy

Parameters:

particle - the particle to update position of

getRadius

public double getRadius()

Returns:

the radius

setRadius

public void setRadius(double radius)

Parameters:

radius - the radius to set
