Detailed Description

template<class POT>
class eoIntegerVelocity< POT >

Integer velocity performer for particle swarm optimization.

Derivated from abstract eoVelocity, At step t: v(t+1)= c1 * v(t) + c2 * r2 * ( xbest(t)-x(t) ) + c3 * r3 * ( gbest(t) - x(t) ) v(t) is an INT for any time step (ci given and Ri chosen at random in [0;1]).

Constructor & Destructor Documentation

template<class POT>
eoIntegerVelocity< POT >::eoIntegerVelocity ( eoTopology< POT > &  _topology,
const VelocityType &  _c1,
const VelocityType &  _c2,
const VelocityType &  _c3,
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 quantify how much the particle trusts itself. Type must be POT::ParticleVelocityType
_c2 - The second learning factor used for the particle's best. Type must be POT::ParticleVelocityType
_c3 - The third 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
