We focus on a situation in which the natural frequencies of the oscilla- tors follow a uniform probability density. By numerically simulating the model, it is shown that the model supports multistable synchronized states such as a traveling wave state, π state and periodic synchronous state： an oscillating π state. The oscillating π state may be characterized by the phase distribution oscillating in a confined region and the phase difference between conformists and contrar- ians oscillating around π periodically. In addition, we present the parameter space of the oscillating state and traveling wave state of the model.展开更多
