摘要
The problem of efficiently monitoring the network flow is regarded as the problem to find out the minimum weighted weak vertex cover set for a given graph G = (V, E). In this paper, we give an approximation algorithm to solve it, which has the approximation ratio In d+ 1, where d is the maximum degree of the vertex in graph G, and improve the previous work.
