Overview

About
Maintained by Viviane PhilippsFirst published 2012-05-109 releasesCRAN page ↗GitHub ↗

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. See Philipps et al, 2021 doi:10.32614/RJ-2021-089.
