Bike-Sharing Static Rebalancing by Considering the Collection of Bicycles in Need of Repair

Algorithm 3

Hybridization of DPSO with VNS.

Input: Based data of bike system, DPSO parameters

Output: The best optimization solution (routes of the bike system)

Begin

 Initialize the population of the swarm, known as Pop and the relative parameters i.e., max iteration

 Apply the initial particle swarm algorithm to represent each particle in

 Calculate the personal best particle in and obtain the personal best of each particle, stored in

 Calculate the global best particle in and obtain the global best of each particle, stored in

 While   do

  Begin

   Update particles using Eq. (21) and Eq. (22)

Apply the initial particle swarm algorithm to evaluate the updating particles

Apply the Local search algorithm(VNS) to optimize the personal best particles

Update the Global best
