  "Description": "An R interface to weighted nonlinear least-squares\noptimization with the GNU Scientific Library (GSL), see M.\nGalassi et al. (2009, ISBN:0954612078). The available trust\nregion methods include the Levenberg-Marquardt algorithm with\nand without geodesic acceleration, the Steihaug-Toint conjugate\ngradient algorithm for large systems and several variants of\nPowell's dogleg algorithm. Multi-start optimization based on\nquasi-random samples is implemented using a modified version of\nthe algorithm in Hickernell and Yuan (1997, OR Transactions).\nRobust nonlinear regression can be performed using various\nrobust loss functions, in which case the optimization problem\nis solved by iterative reweighted least squares (IRLS).\nBindings are provided to tune a number of parameters affecting\nthe low-level aspects of the trust region algorithms. The\ninterface mimics R's nls() function and returns model objects\ninheriting from the same class.",
