There have been several messages on R-devel mentioning the interior point optimization software Ipopt, https://projects.coin-op/Ipopt/. This C++ library is released under a license called the Common Public License.

I have two questions that readers of R-devel may be able to answer.

  1. Would creating an Ipopt interface for R be duplicating existing efforts? That is, has someone already done so or is already working on this project.
  2. Could a package incorporating Ipopt be released under some version of the GPL or LGPL?

Assuming that the answers to those questions are no and yes, I would be willing to mentor a student in a Google Summer of Code project to create such a package. However, I don't have a whole lot of time to do so and would not object at all if another potential mentor, or perhaps a co-mentor, were to volunteer. Failing that I will create an application, including a programming exercise.
