Detailed Description

This class implements the bound handling strategy hyperbolic for the particle swarm optimization.

This bound handling strategy applies at each step. For each dimension the new velocity vel[i] is scaled by 1/(|vel[i]/av| +1), where av is the distance to the search space bound in direction of the velocity. As this bound handling strategy already adjusts the velocity no further velocity adjustment is applied. The new position is calculated by adding the adjusted new velocity to the old position.

Member Function Documentation

std::string highprecisionpso::BoundHandlingHyperbolic::GetName ( )

virtual

Returns a string representation of this object.

Returns

The name of the object.

Implements highprecisionpso::BoundHandling.

void highprecisionpso::BoundHandlingHyperbolic::SetParticleUpdate ( Particle *  p )

virtual

Updates the position of the particle p according to the current position and the new (already calculated) velocity.

First the new velocity vel[i] is scaled by 1/(|vel[i]/av| +1), where av is the distance to the search space bound in direction of the velocity. As this bound handling strategy already adjusts the velocity no further velocity adjustment is applied. The new position is calculated by adding the adjusted new velocity to the old position.

Parameters

p	The particle, which should be updated.

Implements highprecisionpso::BoundHandling.
