Complex of abstract cubes and median problem [PDF]

open access: yesComputer Science Journal of Moldova, 2011
In this paper a special complex $\mathcal{K}^{n}$ of abstract cubes [2, 3], which contains only $n$-dimensional cubes is examined. The border of this complex is an abstract $(n-1)$-dimensional sphere.

Optimizing compatible sets in wireless networks through integer programming

open access: yesEURO Journal on Computational Optimization, 2014
In wireless networks, the notion of compatible set refers to a set of radio links that can be simultaneously active with a tolerable interference. Finding a compatible set with maximum weighted revenue from the parallel transmissions is an important ...

Eccentricity of Networks with Structural Constraints

open access: yesDiscussiones Mathematicae Graph Theory, 2020
The eccentricity of a node v in a network is the maximum distance from v to any other node. In social networks, the reciprocal of eccentricity is used as a measure of the importance of a node within a network.

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 $G$.

Caterpillars Have Antimagic Orientations

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
An antimagic labeling of a directed graph D with m arcs is a bijection from the set of arcs of D to {1, …, m} such that all oriented vertex sums of vertices in D are pairwise distinct, where the oriented vertex sum of a vertex u is the sum of labels of ...

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 ...

A novel algebraic technique for adjacency matrices of some derived graphs

open access: yesMathematical and Computer Modelling of Dynamical Systems
Graph energy has been the main concern of spectral graph theory in the last five decades. The classical graph energy is the sum of the absolute values of the eigenvalues of the adjacency matrix. In many research papers, different versions of graph energy
