Detailed Description

template<class POT>
class eoStandardVelocity< POT >

Standard PSO velocity performer.

Derivated from abstract eoVelocity, At step t: v(t+1)= v(t) + delta1* ( xbest(t)-x(t) ) + delta2* ( gbest(t) - x(t) ) with delta1= c1 * R1 and delta2= c2 * R2 (ci given and Ri chosen at random in [0;1]).

Constructor & Destructor Documentation

template<class POT>

eoStandardVelocity< POT >::eoStandardVelocity	(	eoSingleParticleArchive< POT > &	_archive,
		eoRealVectorBounds &	_bounds,
		const double	_c1 = 0.5,
		const double	_c2 = 0.9,
		eoRng &	_gen = rng
	)			[inline]

Constructor: Only one global best is given thanks to an eoSingleParticleArchive.

Also needs c1 and c2 coefficients and the bounds.

Parameters:

	_archive	- The archive that stored the swarm's global best
	_bounds	- An eoRealVectorBounds: bounds for the velocities
	_c1	- The particle best coeff as a double, default=0.5
	_c2	- The global best coeff ad a double, default=0.9
	_gen	The eo random generator
