%description
This algorithm provides a numerical solution to the problem of
unconstrained local minimization (or maximization). It is particularly
suited for complex problems and more efficient than the Gauss-Newton-like
algorithm when starting from points very far from the final minimum (or
maximum). Each iteration is parallelized and convergence relies on a
stringent stopping criterion based on the first and second derivatives.
