Embodiments perform real-time vertex connectivity checks in graph data representations via a multi-phase search process. This process includes an efficient first search phase using landmark connectivity data that is generated during a preprocessing phase. Landmark connectivity data maps the connectivity ...
Connectivity-Based Segmentation in Large-Scale 2-D/3-D Sensor Networks: Algorithm and Applications Efficient sensor network design requires a full understanding of the geometric environment in which sensor nodes are deployed. In practice, a large-scale s... H Jiang,T Yu,C Tian,... - 《IEEE...
We describe algorithms and data structures for maintaining information about 2- and 3-vertex-connectivity, and 3- and 4-edge-connectivity in a planar graph in O(n1/2) amortized time per insertion, deletion, or connectivity query. All of the data structures handle insertions that keep the ...
On the minimum local-vertex-connectivity augmentation in graphs Given a graph G and target values r(u,v) prescribed for each pair of vertices u and v, we consider the problem of augmenting G by a smallest set F of new e... Hiroshi,Nagamochi,and,... - 《Discrete Applied Mathematics》...
Vertex cover Connectivity Parameterized algorithms Kernels Approximate kernels Approximation algorithms 1. Introduction For a graph , a set is a vertex cover if for every edge at least one of the vertices belongs to C. The well-known classical Vertex Cover problem is the problem of deciding whether...

the authors give the cyclic vertex connectivity of Cartesian product of two connected graphs as follows:(1)If G_1≌K_m and G_2≌K_n,them κ_c(G_1×G_2)=min{3m+n-6,m+3n-6},for m+n≥8,and m≥n+2,or n≥m+2,and κ_c(G_1×G_2)=2m+2n-8,for m+n≥8 and m=n,...
The class of star graphs is a popular topology for interconnection networks. However it has certain deficiencies. A class of generalization of star graphs called (n, k)-star graphs was introduced in [12] to address these issues. In this paper we will consider the vertex-connectivity of the ...
