#' A parallelized general-purpose optimization based on Marquardt-Levenberg algorithm
#'
#' This algorithm provides a numerical solution to the problem of unconstrained local
#' minimization/maximization. This is more efficient than the
#' Gauss-Newton-like algorithm when starting from points very far from the final
#' minimum/maximum. A new convergence test
#' is implemented (RDM) in addition to the usual stopping criterion : stopping
#' rule is when the gradients are small enough in the parameters metric
#' (GH^{-1}G).
