%0 Journal Article %T A comparative study on optimization methods for the constrained nonlinear programming problems %A Yeniay Ozgur %J Mathematical Problems in Engineering %D 2005 %I Hindawi Publishing Corporation %X Constrained nonlinear programming problems often arise in many engineering applications. The most well-known optimization methods for solving these problems are sequential quadratic programming methods and generalized reduced gradient methods. This study compares the performance of these methods with the genetic algorithms which gained popularity in recent years due to advantages in speed and robustness. We present a comparative study that is performed on fifteen test problems selected from the literature. %U http://www.hindawi.net/access/get.aspx?journal=mpe&volume=2005&pii=S1024123X04407157
