Re: [R] convex optimization package for R, specifically semidefinite programming

Hi there, I do assume you are talking about the CVXOPT (and CVXMOD) Python package(s). Please note that CVXOPT only contains _interfaces_ to the solvers in MOSEK, because these are commercial products (as Roger Koenker already has mentioned). There appear to be some Python/Scipy-based solvers

[R] convex optimization package for R, specifically semidefinite programming

2007-11-14 Thread Galkowski, Jan
Recently, a package for convex optimization was announced for Python, based upon the LP solver GLPK, the SDP solver in DSDP5, and the LP and QP solvers in MOSEK. I'm aware GLPK is available for R, but wondered if anyone had good packages for convex optimization along these lines for R. TIA.

Convex optimization is a large problem domain with many interesting new developments, and MOSEK is a particularly good implementation of many of these developments. It is quite easy to get R to speak to MOSEK via R.matlab -- i've been doing this recently for some work on density estimation,
