Detailed Description

template<class POT>
class eoStandardVelocity< POT >

Standard PSO velocity performer.

Derivated from abstract eoVelocity, At step t: v(t+1)= v(t) + c1*r1* ( xbest(t)-x(t) ) + c2*r2* ( gbest(t) - x(t) ) (ci given and Ri chosen at random in [0;1]).

Constructor & Destructor Documentation

template<class POT>

eoStandardVelocity< POT >::eoStandardVelocity	(	eoTopology< POT > &	_topology,
		const VelocityType &	_c1,
		const VelocityType &	_c2,
		eoRealVectorBounds &	_bounds,
		eoRealBoundModifier &	_bndsModifier,
		eoRng &	_gen = `rng`
	)			`[inline]`

Full constructor: Bounds and bound modifier required.

Parameters:

	_topology	- The topology to get the global/local/other best
	_c1	- The first learning factor used for the particle's best. Type must be POT::ParticleVelocityType
	_c2	- The second learning factor used for the local/global best(s). Type must be POT::ParticleVelocityType
	_bounds	- An eoRealBaseVectorBounds: real bounds for real velocities. If the velocities are not real, they won't be bounded by default. Should have a eoBounds ?
	_boundsModifier	- An eoRealBoundModifier used to modify the bounds (for real bounds only).
	_gen	- The eo random generator, default=rng
