[Rd] [SoC09-Info] An IPopt interface for R

[Douglas Bates]

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.
