Status of RUBI integrator

[Naveen Saisreenivas Thota]

Hi,

I was going through some issues of symengine when I came across the RUBI integrator. It would be a huge addition to the library. However, I couldn't quite understand the current status of the implementation. I have a 3-month long break from the beginning of December, and I am relatively free, so I would like to work on this. Could someone tell me -

1. What is the current status of RUBI in symengine?

2. How are we planning to integrate it into Sympy?

3. What are the prerequisites(if any) to work on this?

Regards

Thanks for the email and your interest!

The latest status update, as far as I understand it is in my comment here:

https://github.com/symengine/symengine/issues/1597#issuecomment-521721092

By wrapping it in Python wrappers, just like any other functionality in SymEngine.

I don't think there are any prerequisites, besides those mentioned in the comment link above.

Let me know if you want to discuss this further. We can do a video call.

The RUBI developers are working on RUBI 5, which does not rely on the
Mathematica pattern matching capabilities. See recent messages in
https://gitter.im/Rule-Based-Integration/Lobby.

Hi Ondrej,

My vacation starts in about 2 weeks, so meanwhile I'll go through the code properly and try to get myself familiarized. Once I'm free, I'll message you and we can have a video call as to what to do. Now that Aaron has talked about RUBI 5, I asked on RUBI's gitter about the expected completion date. It might be best to wait until it releases.

Regards

Naveen
