From: CUFID-query: accurate network querying through random walk based network flow estimation

Estimating the steady-state network flow based on the CUFID framework. Red arrows indicate the random walk within the query or the target network, while the green arrows represent the random walk across two networks. The correspondence between two nodes – one in the query network and the other in the target network – can be estimated by measuring the steady-state network flow through the pseudo-edges connecting the nodes
