Algorithm 2

CAO procedure.

Step  1. Initialization (configure parameters, initialize QOT, VCN, and initialize the initial position of

     all ants)

Step  2. While iteration t < maximum iterations do:

     Calculate the next position of ants according to the equation (8).

     Calculate the fitness value of every candidate solution.

     Update pheromone matrix according to equation (10).

Step  3. End while

Step  4. Select the optimal solution and return.
