Optimal box-covering algorithm for fractal dimension of complex networks
Optimal box-covering algorithm fractal dimension complex networks Computational Physics
2012/4/24
The self-similarity of complex networks is typically investigated through computational algorithms the primary task of which is to cover the structure with a minimal number of boxes. Here we introduce...
Parallel-tempering cluster algorithm for computer simulations of critical phenomena
Parallel-tempering cluster algorithm computer simulations critical phenomena
2011/8/18
Abstract: In finite-size scaling analyses of Monte Carlo simulations of second-order phase transitions one often needs an extended temperature range around the critical point. By combining the paralle...
A One-Dimensional Local Tuning Algorithm for Solving GO Problems with Partially Defined Constraints
Global optimization multiextremal constraints geometric algorithms index scheme local tuning
2011/8/18
Abstract: Lipschitz one-dimensional constrained global optimization (GO) problems where both the objective function and constraints can be multiextremal and non-differentiable are considered in this p...
The classical EMD algorithm has been used extensively in the literature to decompose signals that contain nonlinear waves. However when a signal contain two or more frequencies that are close to one a...

Rest Frame Subjet Algorithm SISCone Jet For Fully Hadronic Decaying Higgs Search
2011/1/5
The rest frame subjet algorithm is introduced to de ne the subjets for the SISCone jet. Using it,an IR and collinear safe jet shape observable N-subjettiness, j N, is de ned to discriminate the fat ...
Variable time amplitude amplification and a faster quantum algorithm for solving systems of linear equations
amplitude faster quantum algorithm equations
2010/11/8
We present two new quantum algorithms. Our first algorithm is a generalization of amplitude amplification to the case when parts of the quantum algorithm that is being amplified stop at different time...
Exactness of the Original Grover Search Algorithm
Exactness Original Grover Search Algorithm
2010/11/5
It is well-known that when searching one out of four, the original Grover's search algorithm is exact; that is, it succeeds with certainty. It is natural to ask the inverse question: If we are not sea...
