Abstract: A new kind of collective intelligent function optimization method is proposed，which is based on Bacterial Colony Foraging Rule and Bacterial Chemotaxis（BC） algorithm，and named as Polymorphic BC（PBC） algorithm.The PBC conquers the deficiencies of BC which converges too slowly and falls into local extrema easily.Simulations on different test functions show that the PBC algorithm is a kind of potentially powerful optimization method worthy of further research，and performs better than GA，PSO，and BC.
