A $4/3$ Approximation for $2$-Vertex-Connectivity [PDF]

open access: yesTheoretiCS
The 2-Vertex-Connected Spanning Subgraph problem (2VCSS) is among the most basic NP-hard (Survivable) Network Design problems: we are given an (unweighted) undirected graph $G$.

The Serial Transitive Closure Problem for Trees

open access: yes, 2002
The serial transitive closure problem is the problem of, given a directed graph G and a list of edges, called closure edges, which are in the transitive closure of the graph, to generate all the closure edges from edges in G.

Revisiting structure graphs: Applications to CBC-MAC and EMAC

open access: yesJournal of Mathematical Cryptology, 2016
In [2], Bellare, Pietrzak and Rogaway proved an O⁢(ℓ⁢q2/2n)${O(\ell q^{2}/2^{n})}$ bound for the PRF (pseudorandom function) security of the CBC-MAC based on an n-bit random permutation Π, provided ...

Labeling schemes for small distances in trees

open access: yes, 2003
. We consider labeling schemes for trees, supporting various relationships between nodes at small distance. For instance, we show that given a tree T and an integer k we can assign labels to each node of T such that given the label of two nodes we can ...

An Asymptotically Optimal Minimum Degree Ordering of Regular Grids

open access: yes, 1995
It has previously been shown that there exists a minimum degree ordering for regular grids that is considerably worse than nested dissection in terms of fill-in and operations for factorization [1].

Partitioning of finite element meshes for parallel computing: A case study

open access: yes, 1997
. The realization of the finite element method on parallel computers is usually based on a domain decomposition approach. This paper is concerned with the problem of finding an optimal decomposition and an appropriate mapping of the subdomains to the ...

Network structural properties and their application to missing property prediction [PDF]

open access: yes, 2013
The volume of available structured data is increasing, particularly in the form of Linked Data, where relationships between individual pieces of data are encoded by a graph-like structure.
