Improving Vector Evaluated Particle Swarm Optimisation Using Multiple Nondominated Leaders

Algorithm 1

The PSO algorithm.

begin

  Initialise position & velocity;

  Evaluate objective;

  Initialise pBest;

  Initialise gBest (2);

  while  𝑖≤𝑖_max  do

    Update velocity (3);

    Update position (4);

    Evaluate objective;

    Update pBest;

    Update gBest (2);

     𝑖 ++;

  end
