A Link Stress-related Virtual Network Embedding Algorithm [PDF]

open access: yesJisuanji gongcheng, 2016
Aiming at the problem of high link stress in substrate network caused by traditional Virtual Network Embedding(VNE) algorithm,a new VNE algorithm is proposed.In the stage of node embedding,the importance degree of node in network is gotten by its ...

Parameterized Algorithms for Book Embedding Problems [PDF]

open access: yesJournal of Graph Algorithms and Applications, 2019
A $k$-page book embedding of a graph $G$ draws the vertices of $G$ on a line and the edges on $k$ half-planes (called pages) bounded by this line, such that no two edges on the same page cross. We study the problem of determining whether $G$ admits a $k$-page book embedding both when the linear order of the vertices is fixed, called ${\rm F{\small IXED}

Embedding cube-connected cycles graphs into faulty hypercubes [PDF]

open access: yes, 1994
We consider the problem of embedding a cube-connected cycles graph (CCC) into a hypercube with edge faults. Our main result is an algorithm that, given a list of faulty edges, computes an embedding of the CCC that spans all of the nodes and avoids all of

Local procrustes for manifold embedding: a measure of embedding quality and embedding algorithms [PDF]

open access: yesMachine Learning, 2009
We present the Procrustes measure, a novel measure based on Procrustes rotation that enables quantitative comparison of the output of manifold-based embedding algorithms (such as LLE (Roweis and Saul, 2000) and Isomap (Tenenbaum et al, 2000)). The measure also serves as a natural tool when choosing dimension-reduction parameters.

An Uniform Embedding Steganography Algorithm Based on Block Entropy [PDF]

open access: yesJisuanji gongcheng, 2017
In Uniform Embedding Revisited Distortion(UERD) algorithm,the distortion function only considers the number of nonzero coefficients and does not take into account the influence of the statistical distribution on the embedding position,so this paper ...

Memetic Multi-Objective Particle Swarm Optimization-Based Energy-Aware Virtual Network Embedding [PDF]

open access: yes, 2015
In cloud infrastructure, accommodating multiple virtual networks on a single physical network reduces power consumed by physical resources and minimizes cost of operating cloud data centers. However, mapping multiple virtual network resources to physical

Large-scale wave-front reconstruction for adaptive optics systems by use of a recursive filtering algorithm [PDF]

open access: yes, 2005
We propose a new recursive filtering algorithm for wave-front reconstruction in a large-scale adaptive optics system. An embedding step is used in this recursive filtering algorithm to permit fast methods to be used for wave-front reconstruction on an ...
