Competition between global and asymmetric local interactions among bistable units brings about the characteristic collective behavior: the state of each unit is nonsteady, while their average property remains almost constant. The existence of noise is necessary for sustaining this nonsteady bistable dynamics. In the dynamics, the interface motion between the two different stable states is characterized. The difference from the case with global and diffusive (symmetric) local interactions is discussed.
