@chenchfort, that's a good thing in my opinion. Can you post the log, so that we could fix those?
@srajangarg, you can't do sudo in travis. Instead you can add it as an addon

@srajangarg, you don't need to run the script on all platforms. Just linux would do

@isuruf Ok. I’ll open an issue.

@isuruf what changes should you suggest I make in my proposal?

@isuruf - I'd commented on your post on the Google group, and was hoping for a response today

Basic functionality I'd like to see is,
Reproduce type hierarchy of all the classes in Haskell
Operator overloading (eg. x + 1 where x is a SymEnginne Symbol and 1 is a Haskell int)
Haskell Int, floats, complex <-> SymEngine
Numerical evaluations
All the functions in functions.h
Matrices
Lambdify
@srajangarg, your proposal link is out of date

@isuruf sorry about that. Can you check again?

@badcoderparashar, in the timeline, saying that you will work on the project is not enough, it should indicate what you will be working on. For example, work on a SymEngineConverter similar to SymPy Converter, etc.

I really don't know about the vision of the polynomial class for SymEngine in future. I was studying about the fast algorithms for polynomial manipulation the past three weeks. Hence, majority of my proposal deals with polynomials with integer and rational coefficients. What do you suggest can be done now, regarding my proposal? And what functionality do you expect from a full fledged polynomial class from SymEngine?

What kind of things can be implemented for polynomials with symbolic coefficients?
Srajan Garg
@srajangarg
Mar 23 2016 11:58
Most of the above algorithms, but with the usual speed. No optimization.
But I feel that isn't a GSoC length project
I can propose to additionaly work on the UnivariatePolynomial class which deals with the symbolic coefficients, alongside my original proposal
I will also have to quickly research into the list of functions for symbolic coefficients.

There is sympy.polys module. You can take a look

@isuruf - just to clarify, you'd like to see this before the project even starts, or just in the proposal?

Most of them in proposal, yes

alright, cool. So I'll edit the proposal tonight and ping you on the group, cool?

@isuruf Can we name methods differently ?

It will ease the task and also the code that I have commented in symengine/SymEngine.jl#16 will then be apt for our needs

I have submitted a draft proposal on GSoC's website. Please comment your take on the proposal. You can comment on the draft itself, or can notify me here on gitter. Thanks!
