WebIn this paper we consider the problem of computing a minimum cycle basis of an undirected graph G = ( V, E) with n vertices and m edges. We describe an efficient implementation of an O ( m 3 + mn 2 log n) algorithm presented in [1]. For sparse graphs this is the currently best known algorithm. WebThis work considers the problem of computing a minimum cycle basis of an undirected non-negative edge-weighted graph G with m edges and n vertices and designs an O(mn + mn …
Webof the weights of its edges. The weight of a cycle basis is the sum of the weights of its cycles. We consider the problem of computing a cycle basis of minimum weight in an undirected graph. (We use the abbreviation MCB to refer to a minimum cycle basis.) The problem has been extensively studied, both in its general setting and in 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.
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. WebOct 24, 2024 · Optimal Cycle Basis: a basis that corresponds to maximal sparsity of cycle adjacency matrix, D, is called an optimal cycle basis. A cycle basis corresponding to near maximum sparsity of D is called a suboptimal cycle basis. An optimal cycle basis is not necessarily a minimal cycle basis and vice versa. 9.3.2 Simulated Annealing Algorithm
