The cooperative behavior of a network of interacting nonlinear oscillators is investigated numerically. Such an oscillator-net serves as a phenomenological modelfor an endogenous circadian pacemaker in organisms. Following two types of network are examined. (1) Ordered oscillator-net: oscillators sit on the square-latticepoints and interact with the nearest neighbors. (2) Random oscillator-net: eachoscillator is influenced by a certain number of randomly chosen oscillators. Detailedcomputer experiment is made on the oscillator-net containing one hundred to onethousand oscillators. The self-entraining behavior is found to be very different in thetwo types of oscillator-net. The sample- and size-dependence are also studied. Therelevance of the oscillator-net as a model for the circadian pacemaker is discussed.[circadian pacemaker, interacting nonlinear oscillators, self-entrainment, corn- I[ puter experimentl
