A New Nonlinear Equations Test Problem

Abstract

This report presents a set of test problems for nonlinear equations and nonlinear least-squares algorithms. These problems, sent to the authors by C. V. Nelson of the Maine Medical Center, come from a dipole model of the heart. They are 6x6 or 8x8, easy to code, cheap to evaluate, but not easy to solve. In support of the latter contention, they present test results from MINPACK and NL2SOL.
