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.

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.
