Webb7 jan. 2024 · I try the parameter init_pos described in pyswarms documentation. init_pos = np.array (init_pos) #My guess for a initial swarm. In this case, the variable init_pos is an array of size (len (X),). However, when I execute the code. optimizer = ps.single.GlobalBestPSO (n_particles=swarm_size, dimensions=dim, options=options, … WebbIf your function sets stop to true, iterations end.Set stop to false to have particleswarm continue to calculate..
