Solver wish list

[mpowelson]

This is a short wish list of solvers that we could add to trajopt_optimizers. We should also consider pushing some of them back to IFOPT if there is interest in that community.

• [ ] Develop solver interface test suite
• [ ] OptimLib
• [ ] Gurobi interface in trajopt_sqp - We should try SNOPT before we put too much effort into it, but an interface to Gurobi might be nice.
• [ ] Pagmo2 - "A C++ scientific library for massively parallel optimization"
• [ ] HQP - Doesn't look very active, but it is open source (LGPL). It might be worth trying out.
• [ ] HPIPM - BSD licensed interior point solver. THIS package has an interface to it that may be used as a reference.
• [ ] SOLNP - "This is a C++ implementation of the SOLNP algorithm by Yinyu Ye (1989) with Python Wrappers. The algorithm was originally implemented in Matlab, and have gained some fame through it's R implementation (RSOLNP). Various implementations of the algorithm exists already, however, this version utilizes the power of DLIB and C++11."
• [ ] Optizelle - "An open source software library designed to solve general purpose nonlinear optimization problems of the form"

This web page has many options that we could explore

If anyone goes looking, I've got the start of a pagmo interface here.
