This makes optimization transparent for the user as the corresponding workflow is abstracted from the underlying solver. The approach allows for easy switching between solvers and thus enhances comparability. For more information see the ROI home page. It allows the user to formulate convex optimization problems in a natural way following mathematical convention and DCP rules. The system analyzes the problem, verifies its convexity, converts it into a canonical form, and hands it off to an appropriate solver such as ECOS or SCS to obtain the solution.

BB contains the function spg providing a spectral projected gradient method for large scale optimization with simple constraints. It takes a nonlinear objective function as an argument as well as basic constraints. GrassmannOptim is a package for Grassmann manifold optimization. The implementation uses gradient-based algorithms and embeds a stochastic gradient method for global search. It optimizes real-valued functions over manifolds such as Stiefel, Grassmann, and Symmetric Positive Definite matrices. It uses a "line search" approach via the function multimin.

Several derivative-free optimization algorithms are provided with package minqa ; e. In package trust , a routine with the same name offers local optimization based on the "trust region" approach. The algorithm is optimized for objective functions with sparse Hessians. This makes the algorithm highly scalable and efficient, in terms of both time and memory footprint. Package quantreg contains variations of simplex and of interior point routines nlrq , crq. It provides an interface to L1 regression in the R code of function rq.

QP solves quadratic programming problems with linear equality and inequality constraints. The matrix has to be positive definite. The matrix can be positive semidefinite. Dykstra's cyclic projection algorithm for positive definite and semidefinite matrices. The routine allows for a combination of equality and inequality constraints. Package funconstrain on Github implements 35 of the test functions by More, Garbow, and Hillstom, useful for testing unconstrained optimization methods. Least-Squares Problems Function solve.

Package nlsr provides tools for working with nonlinear least-squares problems. Functions nlfb and nlxb are intended to eventually supersede the 'nls ' function in Base R, by applying a variant of the Marquardt procedure for nonlinear least-squares, with bounds constraints and optionally Jacobian described as R functions. It is based on the now-deprecated package nlmrt. Package minpack. Functions for solving quadratic programming problems are also available, which transform such problems into least squares ones first.
