“…In the following, calculate the P-best of each particle and g-best of population (the best movement of all particles). The updated velocity, position, g-best and p-best of particles give a new best position (best chromosome in our proposition) Figure (2) shows the PSO model for microstrip antenna and Figure (3) shows the PSO algorithm for microstrip Antenna Design, the PSO algorithm can be described as: [13,19,20]. For fast convergence of PSO iteration, the initial particle can include with random position and velocity.…”
