No algorithm for optimizing general nonlinear functions exists that will always find the global optimum for a general nonlinear minimization problem in a reasonable amount of time. Since no single ...

9 NLPNRA: specifies the number of rows returned by the sparse Hessian module 10 NLPNMS, NLPQN: specifies the total number of constraints returned by the "nlc" module 11 NLPNMS, NLPQN: specifies the ...

Abstract: In this article, we propose a method for the online nonlinear chromaticity correction at store in the relativistic heavy ion collider (RHIC). With 8 arc sextupole families in each RHIC ring, ...

Abstract: This paper explores the potential of a nonlinear optimization algorithm, known as the Levenberg-Marquardt (LM) algorithm, to expedite the calculation of spherical wave coefficients.

This article proposes an optimization model for simultaneous estimation of an origin-destination (O-D) matrix and a travel-cost coefficient for congested networks in a logit-based stochastic user ...
