Comparison of the conventional PSO and QPSO.

Algorithms	Items	Descriptions
Conventional PSO	Formulas
		Operators	Particle generation ( and ), velocity update, and position update
	Critical parameters	Acceleration coefficients and
		Inertia weights
	Remarks	Velocity vector is required
	QPSO	Formulas	[Type 2-I]
Operators			Particle generation ( and ), mean best position calculation, and position update
Critical parameters			The contraction expansion coefficient
Remarks		Velocity vector is not required
