+  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.
