Given an undirected graph G = (V, E), its edge connectivity eta (G) is the least k such that there are k edges whose removal disconnects G. (eta (G) = 0 for graphs that are not already connected: eta (G) = 1 for trees.) Show how to compute eta (G) by solving at most |V| max-flow problems on capacitated networks with O (|V|) vertices and O (|E|) edges. (Note, capacitated networks are allowed to have antiparallel edges-in keeping with the definitions in lecture, and in contrast with the definitions for flow networks (which is the same thing as capacitated networks) in the CLRS textbook.)
