Conditions that impact the complexity of QoS routing

FA Kuipers, PFA Van Mieghem - IEEE/ACM transactions on …, 2005 - ieeexplore.ieee.org
Finding a path in a network based on multiple constraints (the MCP problem) is often
considered an integral part of quality of service (QoS) routing. QoS routing with constraints …

A Percus, G Istrate, C Moore - 2006 - books.google.com
Computer science and physics have been closely linked since the birth of modern
computing. In recent years, an interdisciplinary area has blossomed at the junction of these …

The impact of correlated link weights on QoS routing

FA Kuipers, P Van Mieghem - IEEE INFOCOM 2003. Twenty …, 2003 - ieeexplore.ieee.org
Finding a path in a network based on multiple constraints (the MCP problem) is often
referred to as QoS routing. QoS routing with constraints on multiple additive metrics has …

probabilistic model due to Molloy [Models for random constraint satisfaction problems, in …

Phase transition and computational complexity in a stochastic prime number generator

L Lacasa, B Luque, O Miramontes - New Journal of Physics, 2008 - iopscience.iop.org
We introduce a prime number generator in the form of a stochastic algorithm. The character
of this algorithm gives rise to a continuous phase transition which distinguishes a phase …

A brief description of a software tool developed to analyze transmission lines with arbitrary
losses is presented in this paper. This tool summarizes a complete methodology for the …

Coarse and sharp thresholds of boolean constraint satisfaction problems

G Istrate - arXiv preprint cs/0503083, 2005 - arxiv.org
We study threshold properties of random constraint satisfaction problems under a
probabilistic model due to Molloy. We give a sufficient condition for the existence of a sharp …

Complex Systems, numbers and Number Theory

L Lacasa, B Luque… - Reviews of Nonlinear …, 2010 - Wiley Online Library
Much ink has dried in the historical discussion of what is mathematics? Does it follows the
scientific method? Is it just a collection of recipes, formulas and algorithms? Is it a science or …

Crossover phenomenon in the performance of an Internet search engine

L Lacasa, J Tagliabue, A Berdahl - arXiv preprint arXiv:1205.1505, 2012 - arxiv.org
In this work we explore the ability of the Google search engine to find results for random N-
letter strings. These random strings, dense over the set of possible N-letter words, address …
