Detailed Description

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

If a particle would leave the search space on one side, it will enter the search space on the other side. The movement is similar to modular arithmetic.

Member Function Documentation

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

virtual

Calculates the difference vector between the position and the aim.

As the search space repeats, the aim can be reached in positive direction as well as in negative direction. The value with smaller absolute value counts as the difference in that dimension.

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 from highprecisionpso::BoundHandling.

std::string highprecisionpso::BoundHandlingTorus::GetName ( )

virtual

Returns a string representation of this object.

Returns: The name of the object.

Implements highprecisionpso::BoundHandling.

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

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 torus is activated. If a particle would leave the search space on one side, it will enter the search space on the other side. The movement is similar to modular arithmetic. No velocity adjustment is executed here.

Parameters

p	The particle, which should be updated.

Implements highprecisionpso::BoundHandling.
