WebSection 4 deals with a-priori length and weight bounds on minimum cycle bases. We will prove results of the following avor: every graph of nnodes and medges has a weakly fundamental cycle basis of length O(mlogm=log(m=n)). We will also show that there are graphs that do not have a shorter basis. WebThe all-pairs min cut (APMC) problem on a nonnegative weighted graph is the problem of finding, for every pair of nodes, the min cut separating the pair. It is shown that on planar graphs, the APMC problem is equivalent to another problem, the minimum cycle basis (MCB)problem, on the dual graph.
