Detailed Description

template<class POT>
class eoVariableInertiaWeightedVelocity< POT >

Inertia variable weighted based velocity performer.

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

Constructor & Destructor Documentation

template<class POT>

eoVariableInertiaWeightedVelocity< POT >::eoVariableInertiaWeightedVelocity	(	eoSingleParticleArchive< POT > &	_archive,
		eoRealVectorBounds &	_bounds,
		eoValueParam< unsigned > &	_genCounter,
		const unsigned	_maxGen,
		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 an eoValueParam for the inertia weight.

Parameters:

	_archive	The archive that stored the swarm's global best
	_bounds	- An eoRealVectorBounds: bounds for the velocities
	_genCounter	The generation counter used to perform the inertia weight
	_maxGen	The maximum number of iterations.
	_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, default=rng
