Attractor distributions in random GRNs.

Asymptotic states reached by tests with random network structures, parameter distributions and initial variable conditions for D GRNs with , and . The asymptotic states are classified into three types: steady, periodic oscillatory and chaotic states. Most tests tend to stable steady states and much less periodic oscillations. The probability of oscillations is computed out, and the amount of chaotic samples is counted out of every tests. The asymptotic chaotic states are extremely rare indeed.
