| Abstract(in English) | We model a phenomenon that a computer virus is spreading in a network as infection of the virus in a graph constructed of nodes and edges. We consider estimating the source of infection from the nodes infected by the virus. In previous studies, it was assumed that the prior distribution of the source is uniform. For regular trees, the optimal estimation method was shown in order to estimate the source of the infection from the nodes. In this paper, we consider the case that the prior distribution is not necessarily uniform. For regular trees, we clarify the correct detection probability for some cases with the optimal estimation method. Moreover, we compare the obtained correct detection probability with that of a previous result by numerical computation, and show the improve of the correct detection probability. |
