I read your paper on researchgate a few months ago and recently came across this project on github. I have the following questions.

Are there any plans for releasing a interface in python?
From my experience of solving trajectory optimization problem, IPOPT happens to be by far the most reliable solver I have encountered. It converges to a solution (local )even when bad guesses are supplied. Can uno compete against IPOPT?

It would be great if the uno solver can be integrated into casadi which provides interfaces to several NLP solvers.

Dear Sandeep,

Thanks for reaching out.

I'm planning to develop a Python interface this year (I'm on parental leave, back to work in March).
Uno mimics the method implemented in IPOPT and the performance is very similar (see here). At the moment we're not quiiiiite as robust (of the 429 test problems we consider, about 10 are solved by IPOPT but not by Uno). There's a small bug I need to fix and there's also a certain number of small tricks that I didn't implement. That said, I have a couple of ideas of how I can improve the IPOPT algorithm and I'm hoping that at some point, Uno will surpass IPOPT. We'll see :)

Joris Gillis actually started to interface Uno and CasADi a few months ago. I'm not sure how far along he is, though. Perhaps you can ask him and put me in copy?

Best regards,
