Rupture degree of graphs
We introduce a new graph parameter, the rupture degree. The rupture degree for a complete graph Kn is defined as 1 − n, and the rupture degree for an incomplete connected graph G is defined by r(G) = max{ω(G − X)− |X| − m(G − X) : X ⊂ V(G),ω(G − X) > 1}, where ω(G − X) is the number of components of G − X and m(G − X) is the order of a largest component of G − X . It is shown that this paramete...
متن کاملTenacity and rupture degree parameters for trapezoid graphs
Reliability of networks is an important issue in the field of graph and network. Computation of network vulnerability parameters is NP-complete for popular network topologies such as tree, Mesh, Cube, etc.In this paper, we will show that the tenacity and rupture degree parameters for trapezoid graphs can be computed in polynomial time.
متن کاملA Fast Algorithm to Find All High Degree Vertices in Graphs with a Power Law Degree Sequence
We develop a fast method for finding all high degree vertices of a connected graph with a power law degree sequence. The method uses a biassed random walk, where the bias is a function of the power law c of the degree sequence. Let G(t) be a t-vertex graph, with degree sequence power law c ≥ 3 generated by a generalized preferential attachment process which adds m edges at each step. Let Sa be ...

متن کاملA Heuristic to Find a P%-robust Network Design
Given a network with a set of nodes and a set of potential edges, we must decide what edges will be included in the design to satisfy demands between pairs of nodes. Each edge has associated a finite capacity, a fixed cost and routing costs. Uncertainty will be considered in important input parameters such as demands and routing costs and will be modeled through scenarios. The objective is to f...
