Improving Vector Evaluated Particle Swarm Optimisation Using Multiple Nondominated Leaders

Algorithm 2

The VEPSO algorithm.

begin

  Initilise position & velocity for all M-swarm;

  Evaluate objective for all M-swarm;

  Initialise archive;

  Initialise pBest for all M-swarm;

  Initialise gBest (5) for all M-swarm;

  while   𝑖≤𝑖_max  do

    Update velocity (6) & (7) for all M-swarm;

    Update position (4) for all M-swarm;

    Evaluate objective for all M-swarm;
