The Universal Scalability Law (USL) of computational capacity has been proposed by Neil J. Gunther. USL abstracts the coefficients of inter process interactions and other contentions in the area of parallel and distributed computing in a set of constant parameters { , }. One cannot apply USL for the purpose of predicting performance, unless the values of those constant parameters are known. A computationally light weight and theoretically correct algorithm to estimate those parameters from measured performance data is not available yet. Simple linear-regression or standard least-square-error-approximation is a widely used efficient statistical technique to estimate parameters. A simple linear-regression cannot be applied directly to estimate the coefficients , of USL, because USL is a rational function. In this work, we propose a novel and elegant algorithm based on standard least-square-error-approximation or linear-regression to estimate the parameters. The explanation of failure of simple linear-regression is discussed by visiting the basic theory of linear-regression. A novel approach, consisting of algebraic manipulations to transform the problem into two linear-regression problems, is presented. The linear-regression is applied successively in a certain order to estimate the constant parameters, , , of USL. The proposed technique is applied to a set of measured performance data to validate and verify the proposed technique.
In this paper, a maximal triangle free graph has been generated from the complete graph for by deleting number of edges. In addition, two theorems have been established for it. Finally, an algorithm has been developed under different cases to solve the traveling salesman problem when the weights of the edges are non-repeated of the complete graph for .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
