Detailed Description

This class is an abstract class. It supplies the interface for bound handling strategies of the particle swarm optimization algorithm.

Constructor & Destructor Documentation

virtual highprecisionpso::BoundHandling::~BoundHandling ( )

inlinevirtual

The destructor.

Member Function Documentation

virtual std::vector<mpf_t*> highprecisionpso::BoundHandling::GetDirectionVector ( const std::vector< mpf_t * > &  position, const std::vector< mpf_t * > &  aim  )

virtual

Calculates the difference vector between the position and the aim.

The standard implementation just calculates the aim vector minus the position vector. For bound handling strategies, which simulate repeated search spaces, this could be changed.

Parameters

position	The vector, which describes the position.
aim	The vector, which describes the aim.

Returns

The difference from the position to the aim.

Reimplemented in highprecisionpso::BoundHandlingTorus.

virtual std::string highprecisionpso::BoundHandling::GetName ( )

pure virtual

Returns a string representation of this object.

Returns

The name of the object.

Implemented in highprecisionpso::BoundHandlingRandomForth, highprecisionpso::BoundHandlingAbsorption, highprecisionpso::BoundHandlingRandom, highprecisionpso::BoundHandlingHyperbolic, highprecisionpso::BoundHandlingTorus, highprecisionpso::BoundHandlingNearest, highprecisionpso::BoundHandlingReflect, and highprecisionpso::BoundHandlingNoBounds.

virtual void highprecisionpso::BoundHandling::SetParticleUpdate ( Particle *  p )

pure virtual

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

The new position is calculated by adding the velocity to the position. If the new position would be outside of the search space bounds then the bound handling strategy should be activated. Afterwards the specified velocity adjustment should be activated with suitable parameters.

Warning

Do not forget to call the velocity adjustment method of the velocity adjustment specified in the configuration section.

Parameters

p	The particle, which should be updated.

Implemented in highprecisionpso::BoundHandlingRandomForth, highprecisionpso::BoundHandlingAbsorption, highprecisionpso::BoundHandlingRandom, highprecisionpso::BoundHandlingHyperbolic, highprecisionpso::BoundHandlingTorus, highprecisionpso::BoundHandlingNearest, highprecisionpso::BoundHandlingReflect, and highprecisionpso::BoundHandlingNoBounds.
