Algorithm 1

Begin PSO Algorithm

 Input:    : the function to optimize

     : the swarm size

     : the problem dimension

     : decision variable search range

     : particle velocity limits

 Output:     : the best particle position found (global best)

     : the best fitness value found

 Initialize: position   and velocity , for all particles in problem space

 evaluate in variables and get , ()
