Abstract

Abstract This paper presents a systematic procedure for the comparative performance evaluation of nonlinear programming codes intended for applications in structural optimization. Part I discusses the issues in the evaluation of nonlinear programming codes and proposes a performance evaluation scheme for structural optimization codes. Aspects of performance evaluation such as the choice of test problems and appropriate set of performance criteria for structural optimization codes are described. A procedure to analyze codes based on their observed geometric behavior for test problems is also presented. The proposed method is contrasted with studies conducted in the past for comparative performance evaluation of nonlinear programming codes. Part II presents an application of the theory described in part I to evaluate two design optimization codes.
