Re: [sympy] Re: Query Regarding Contributing towards Sympy

[Aizen]

Thank You for letting me know about it. Perhaps I should also look at other 
topics that can connect with Symbolic Manipulation for which Sympy is 
targetted at.
And I see, we can use some graph algorithms to improve the inner workings 
of sympy. I think to do such stuff we need to learn about all the places 
where optimizations could be done along with their workings. 

Can we open an `optimizations` issue\section under which we can specify all 
optimization issues faced in other modules of the package (from the devs 
who have contributed to that part?) This way we can work on them faster and 
we wouldn't have to explore all the modules(their workings and functions 
used, etc) if we get issues from the people who are already working/using 
them. 
I am saying this because I think (from one of the links you shared which 
specify: `Tarjan's Algorithm`), I would have no way of knowing about such 
possible optimization or algorithm unless I am using the module and I face 
some issue or have knowledge about the function's complexity. Because it is 
always possible that I never explored that discipline implemented in Sympy 
but I can still do some optimization on it.
Also, I will study the issue that you mentioned here, and search for issues 
that are already opened regarding the same.

Re: [sympy] Re: Query Regarding Contributing towards Sympy

[Aizen]

Hello. 
All right, I saw the stats implementation and I need some more theoretic 
background in Stats to be able to contribute to Sympy. But that is a really 
good option for me and I will look into it soon. I will contact you when I 
think I have understood the same for Sympy.
Thanks

Yash

 I have spent time getting familiar with using Sympy regularly. I read 
 the page regarding `Introduction to Contributing`, and it says that I 
 should start by solving issues first(the easy ones). I would love to do 
 that, but the reason I want to contribute is, as I and my peers work in 
 the 
 related stuff and we have to code from scratch every time on similar 
 things. I realized that a lot of people use the same things and it would 
 help if Sympy could provide that.
 I want to introduce some new functionality from another field of 
 mathematics which is not there in Sympy yet, but I believe would be a 
 great 
 addition for people in mathematical and statistical analysis.
 How should I approach towards making a proposal for the same before I 
 start contributing to that functionality, I am no experience about 
 contributing at open source. Should I make an `issue` in the issues 
 section 
 which could later be marked as 'feature-request' by the administrators?
  Please guide me.

 Thanks
