混沌

The ergodicity of chaos is a new and interesting property for optimization, of which the main idea is to search according to a series of successive fields: first search in the total field, then in a smaller one, and so on.

The airflow aroused by a butterfly flapping its wings over southern half-globe maybe lead to tornado over northern half-globe after several weeks' "combination", which is "butterfly effect" in chaos theory. It refers to a phenomenon depending on sensitivity of initial condition: the tittle difference in input will quickly amplify into overwhelming discrimination in fan-out.
