Vertex Degrees in Planar Maps

open access: yes, 2016
We prove a general multi-dimensional central limit theorem for the expected number of vertices of a given degree in the family of planar maps whose vertex degrees are restricted to an arbitrary (finite or infinite) set of positive integers D. Our results rely on a classical bijection with mobiles (objects exhibiting a tree structure), combined with ...

Vertex and edge covers with clustering properties: complexity and algorithms [PDF]

open access: yes, 2009
We consider the concepts of a t-total vertex cover and a t-total edge cover (t≥1), which generalise the notions of a vertex cover and an edge cover, respectively.

Crown reductions for the Minimum Weighted Vertex Cover problem [PDF]

open access: yes, 2004
The paper studies crown reductions for the Minimum Weighted Vertex Cover problem introduced recently in the unweighted case by Fellows et al. [Blow-Ups, Win/Win's and crown rules: some new directions in FPT, in: Proceedings of the 29th International ...

Frugality Ratios and Improved Truthful Mechanisms for Vertex Cover [PDF]

open access: yes, 2007
In set-system auctions, there are several overlapping teams of agents, and a task that can be completed by any of these teams. The auctioneer's goal is to hire a team and pay as little as possible.

Note on the Reformulated Zagreb Indices of Two Classes of Graphs

open access: yesJournal of Chemistry, 2020
The reformulated Zagreb indices of a graph are obtained from the original Zagreb indices by replacing vertex degrees with edge degrees, where the degree of an edge is taken as the sum of degrees of its two end vertices minus 2.

Vertex-Mean Graphs [PDF]

open access: yes, 2011
A graph that has a Smarandachely vertex-mean k-labeling is called Smarandachely k vertex-mean graph or Smarandachely k V -mean graph. Particularly, if k = 0, such a Smarandachely vertex-mean 0-labeling and Smarandachely 0 vertex-mean graph or ...

Parameterized streaming : maximal matching and vertex cover [PDF]

open access: yes, 2014
As graphs continue to grow in size, we seek ways to effectively process such data at scale. The model of streaming graph processing, in which a compact summary is maintained as each edge insertion/deletion is observed, is an attractive one.
