Multiobjective Particle Swarm Optimization Based on PAM and Uniform Design

Algorithm 3

Pseudocode of updating elitist.

population paretoupdate(offspring, pareto)

Input: offspring indicates the offsprings after performing the crossover operator

   and mutation operator; pareto indicates the non-dominated solutions.

Output: pareto indicates the non-dominated solutions.

 for   chr1 offspring;

  nondominated ← true;

  for   chr2 pareto;

   if chr1 dominate chr2

    pareto ← pareto − chr2;

   else if chr2 dominate chr1

    nondominated ← false;

   else

    continue

   end if

  end for

  if nondominated

   pareto ← pareto chr1

  end if

 end for

 return pareto;
