This paper first shows that, given a multigraphGand a vertexswith even degree, all edges incident toscan be split off (i.e., ifGisk-edge-connected, then the resulting multigraph is alsok-edge-connected) inO(mn2+n2logn) time, wherenandmare the numbers of vertices and edges inG, respectively. This algorithm is unique in the sense that it does not rely on the maximum flow computations. Based on this, we then show that, given a positive integerk, the problem of making a multigraphGk-edge-connected by adding the smallest number of new edges can be solved inO(m+minen2+n3logn,kn3) time, wheree(≤n2) is the number of pairs of vertices between whichGhas an edge.
