	EASY-OPT Express | License: Freeware |
	The software system allows to solve constrained nonlinear programming problems by an efficient sequential quadratic programming (SQP) method. A nonlinear objective function is to be minimized subject to nonlinear equality or inequality constraints. The numerical code is called NLPQL, which is frequently used in industry and academia. The mathematical method represents the scientific state-of-the-art. Model functions are defined in a modeling language called PCOMP and are interpreted and evaluated during runtime. It is assumed that all nonlinear functions are differentiable. Gradients are computed automatically. Publisher: Klaus Schittkowski| Date: 15-03-2009 | Size: 60268 KB
