Multiobjective Optimization of Large-Scale EVs Charging Path Planning and Charging Pricing Strategy for Charging Station

Algorithm 4

The PSO algorithm.

	Initialization The particle swarm is initialized with the population amount . Position and velocity of each particle are initialized randomly in the feasible interval. and are initialized as and , respectively. The inertia factor and the acceleration constant are initialized as constants.
(1)	While or
(2)	For each particle , update the position and the velocity as follows,
(3)
(4)	If, Then
(5)	If, Then
(6)
(7)	Output the optimal position and optimized objective
