Algorithm 1. Simple particle swarm optimization (PSO) pseudocode.

1. begin 2. initialize 3. for i in n_iterations = k 4.   for each position p of particle compute fitness 5.     if fitness (p) > fitness (pbest) 6.       pbest = p 7.   set best of pbest as gbest 8.   update particles velocity and position 9. gbest is our result
