Software Listing: Inequality

	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

	EASY-FIT Express | License: Freeware |
	The software system solves constrained nonlinear parameter estimation problems. Synonyms are data fitting, nonlinear regression, parameter identification, curve and surface fitting. The numerical methods are based on highly efficient Gauss-Newton-SQP algorithms. Model functions are defined in a modeling language called PCOMP and are interpreted and evaluated during runtime. General: Arbitrary fitting criteria depending on parameters to be estimated, additional nonlinear equality or inequality constraints, and optionally on a second independent model variable Numerical routines: Gauss-Newton-type SQP methods, automatic differentiation, alternative norms (sum of absolute values, maximum of absolute values), confidence intervals for estimated parameters, correlation and covariance matrix, identification of significance levels for estimated parameters User interface: 'Find' and 'Filter' commands, extensive report and graphics facilities, also for Gnuplot, 3D plots for two model variables (surface fitting), in- and output of data from and to text or Excel files Limitations: 30 fitting criteria and data sets, 100 model variables, 2,000 time values, 3,000 experimental data, 200 linear or nonlinear constraints Modeling language (PCOMP) : Highly flexible statements depending on parameters to be estimated, tabulated data, splines, linear and piecewise constant interpolation Implementation: Numerical routines in Fortran executable outside of the GUI, GUI in VBA, Microsoft Access 2007 run-time version included, database with 240 examples, Windows XP or Vista (contact the author for Win 2K version) .
