Graphical Reduction of Probabilistic Boolean Networks

摘要
We propose a Boolean gossiping model as a simplified yet intriguing probabilistic Boolean network from a graphical reduction perspective. For the case that only positive node interactions are allowed, by standard theories of Markov chains,we prove that the node states almost surely asymptotically converge to an agreement. Using mean-field approximation we characterize the convergent distribution for large-scale networks. The number of states is exponential to the number of nodes in the network. Thus, the calculation of numbers of communication classes seems to be time consuming. Here, we give the exact number of communication classes of any positive Boolean networks. We show that minor variation in local structures can drastically change the number of network communication classes. For general Boolean interaction rules, we provide some examples to indicate the possible conditions under which the Boolean gossiping process are absorbing Markov chains. These results show the possibilities of using graphical methods to fundamentally reduce the computational complexity in deciding behaviors of Boolean networks.
