levmar


Information about the package, levmar, which is shipped with common Linux distributions. The levmar package is designed for, Levenberg-Marquardt nonlinear least squares algorithm.


Package Name:

levmar

Summary:

Levenberg-Marquardt nonlinear least squares algorithm

Description:

levmar is a native ANSI C implementation of the Levenberg-Marquardt optimization algorithm. Both unconstrained and constrained (under linear equations, inequality and box constraints) Levenberg-Marquardt variants are included. The LM algorithm is an iterative technique that finds a local minimum of a function that is expressed as the sum of squares of nonlinear functions. It has become a standard technique for nonlinear least-squares problems and can be thought of as a combination of steepest descent and the Gauss-Newton method. When the current solution is far from the correct on, the algorithm behaves like a steepest descent method: slow, but guaranteed to converge. When the current solution is close to the correct solution, it becomes a Gauss-Newton method.
