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

_topology | - The topology to get the global/local/other best | |
_weightUpdater | - An eoWeightUpdater used to update the inertia weight | |
_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 |

void eoVariableInertiaWeightedVelocity< POT >::operator() | ( | POT & | _po, | |
unsigned | _indice | |||
) | [inline, virtual] |
Evaluate the new velocities of the given particle.
Need an indice to identify the particle into the topology. Steps are :
_po | - A particle | |
_indice | - The indice (into the topology) of the given particle |
Implements eoBF< POT &, unsigned, void >.
