In this section, we discuss how to find the distance between two vertices in an undirected graph. I first explain the algorithm and then reveal its name—BFS. Video Solving a 1600 Difficulty BFS Problem from Co
You are given an undirected graph. Check whether it is bipartite, and if it is, output its sides.Algorithm¶There exists a theorem which claims that a graph is bipartite if and only if all its cycles have even length. However, in practice it's more convenient to use a different ...
In this paper, we prove that the problem of finding a semi-matching that minimizes the maximum load among all vertices in a weighted bipartite graph is NP-complete. A 3 2-approximation algorithm is proposed for this problem.doi:10.1016/j.ipl.2006.06.004Chor Ping Low...
We use it to obtain an algorithm for the bipartite permutation vertex deletion prob- lem with running time O(9k · n9), and also give a polynomial-time 9-approximation algorithm. Keywords Permutation graphs · Comparability graphs · Partially ordered set · Graph modification problems 1 ...
The algorithm is based on the minimum perfect matching problem [3]. It constructs a complete bipartite graph Km,m representing the cost of associating each hyperedge Ik to each potential layout position. A minimum-weight perfect matching would give a one-to-one correspondence between the set of...
If the DNA-A and DNA-B components had been under the same evolutionary pressure, all the points on the graph (Figure 5) would align along the diagonal. However the analysis shows a difference between the distributions of species and isolates. The isolates are scattered along the diagonal (gre...

cerevisiae Hsf1 amino acid sequences using the LIMBO algorithm to identify potential Hsp70-binding sites within the N-AD and C-AD regions (Fig. 6A). Protein fusions were generated between the entirety of the L. kluyveri N-AD or C-AD and the GFP-FLAG moiety. Initially, we expressed the ...
graphbalancedbipartitegraphindependentcycleIn this paper, we obtain the following result: Let k, n1 and n2 be three positive integers, and let G=(V1, V2; E) be a bipartite graph with |V1|=n1 and |V2|=n2 such that n1 2k + 1, n2 2k + 1 and |n1-n2| 1. If d(x) + d(y)...
approximation algorithmA semi-matching on a bipartite graph G = (U∪V, E) is a set of edges X is contained in E such that each vertex in U is incident to exactly one edge in X. The sum of the weights of the vertices from U that are assigned (semi-matched) to some vertex v ∈...
