Order-N method to calculate the local density of states
We present a rigorous and general method to extract the local density of states r i(v) of a system from its time response to a specified external perturbation. This method is order-N when the matrix is sparse. In a single run it gives r i(v),r i(2v), . . . ,r i(nv), . . . concurrently, which enhances the total efficiency by two decades. Application to a lattice-dynamics problem of 4096 SiC part...
متن کاملEfficient, multiple-range random walk algorithm to calculate the density of states.
We present a new Monte Carlo algorithm that produces results of high accuracy with reduced simulational effort. Independent random walks are performed (concurrently or serially) in different, restricted ranges of energy, and the resultant density of states is modified continuously to produce locally flat histograms. This method permits us to directly access the free energy and entropy, is indep...
متن کاملA fast algorithm to calculate the exact radiological
Filip Jacobs was born in Wilrijk (Belgium) in 1970. He graduated in electrical engineering at the University of Ghent in 1994, and obtained a degree in biomedical and clinical engineering techniques in 1996 from the same university. Currently, he's working as a Ph.D. student at the Ignace Lemahieu was born in Varsenare (Belgium) in 1961. He graduated in physics at the University of Ghent in 198...
متن کاملA Fast Algorithm to Calculate Powers of a Boolean Matrix for Diameter Computation of Random Graphs
In this paper, a fast algorithm is proposed to calculate k power of an n× n Boolean matrix that requires O(knp) addition operations, where p is the probability that an entry of the matrix is 1. The algorithm generates a single set of inference rules at the beginning. It then selects entries (specified by the same inference rule) from any matrix Ak−1 and adds them up for calculating correspondin...
متن کاملApplication of the Genetic Algorithm to Calculate the Interaction Parameters for Multiphase and Multicomponent Systems
A method based on the Genetic Algorithm (GA) was developed to study the phase behavior of multicomponent and multiphase systems. Upon application of the GA to the thermodynamic models which are commonly used to study the VLE, VLLE and LLE phase equilibria, the physically meaningful values for the Binary Interaction Parameters (BIP) of the models were obtained. Using the method proposed in t...
