Abstract: By using the Ito formula and the law of iterated logarithm, we studied the dynamic behavior of a class of flocking models disturbed by white noise. Firstly, we proved that the flocking model of two individuals presented unconditional flocking phenomenon. Secondly, for the flocking model of N individuals, we proved that the system had strong random flocking phenomenon under certain conditions.

Key words: flocking model, white noise, Ito formula, dynamic behavior
