Lagrangian Multipliers Convex

TANGO Project web page: http://www.ime.usp.br/~egbirgin/tango/ALGENCAN: Fortran code for general nonlinear programming that does not use matrix manipulations at all and, so, is able to solve extremely large problems with moderate computer time. The general algorithm is of Augmented Lagrangian...

Even if totally m-coded, this routine is particularly fast in computing convex hull of 2D points. In many cases seems to be much faster than the matlab library routine. The main reason is that, differently from convhull, this algorithm jumps the call to unique function which can be very slow for...

This script is capable of solving a convex quadratic programming problem by Wolf's method. For the convergence of the algorithm it is necessary that either Hessian of the objective function be positive definite or positive semidefinite Hessian with linear term zero. For theory of Wolf method and...

VERT2CON - convert a set of points to the set of inequality constraints which most tightly contain the points; i.e., create constraints to bound the convex hull of the given points[A,b] = vert2con(V)V = a set of points, each ROW of which is one pointA,b = a set of constraints such that A*x

This submission contains an interface to a LBFGS solver for unconstrainted minimization problems of the formmin_{x} f(x) + c*|tilde{x}|,where x are the parameters, f is a scalar valued real function, c is a positive scalar (default value=0), |.| denotes the 1-norm, and tilde{x} is some subset of...

The script steepestdescent.m optimizes a general multi variable real valued function using steepest descent method. During the iterations if optimum step length is not possible then it takes a fixed step length as 0.001. For the theory any good book on optimization techniques can be consulted....

The Matlab convhulln is a gateway to the quickhull algorithm ( see www.qhull.org ). In my opinion, one weak point of this mex routine is that it processes all the points without performing any preliminary filtering.In many cases it would be faster if only the point that can be part of the...

This builds a navigation GUI for navigating n-dimensional convex Pareto surfaces interactively. It requires linprog from theoptimization toolbox, but can probably be replaced easily with a free version. The linear programs solved during navigation are very small and easy. It is assumed that all...

The Falling U-Shaped Chain model simulates the dynamics of a discrete falling chain with total length L and n links. Each link is acted on by the force of gravity mg and by the link-link interaction. A freely falling object is released near the last link for comparison. The surprise is that the...

The Lagrangian Pendulum Spring model asks students to solve the Lagrangian for a spring-pendulum and then develop a model of it. It is distributed as a ready-to-run (compiled) Java archive. Double-clicking the ejs_CM_Lagrangian_pendulum_spring.jar file will run the program if Java is installed....
