Hi everyone, I am a third year undergraduate at IIT Kharagpur. I went through the idea list. I am interested to work on any of the two projects below. 1. Solvers 2. Group Theory. Could someone let me know the mentors for these two projects, so that i can discuss with them and finally get sta

I think we should have someone to mentor any of them. For 1 and 3, you may want to reach out to students and mentors that did similar projects in previous years to see what needs to be done. For 2, I believe there are some useful discussions on this mailing list from last year that you should be ab

I have gone through the list of ideas for GSoC 2017. I would be interested to work on any one of the following projects subject to available mentors : 1.Series Expansions 2.Cylindrical Algebraic Decomposition 3.Efficient Groebner Bases and their Application. If any mentor is interested in mento

The algorithms currently implemented have the following best case scenarios for factorizing: - Fermat's Test (When two prime numbers are close to each other) - Pollard's Rho (When one prime factor is much smaller than the other) - Pollard's p-1 (p&q are prime factors -> p-1 divisble by r!, q-1 no

This is something I'm working on for algebraic expressions at the moment. Coming up with a rules based solving mechanism has been proven to be quite a bit challenging as I'm interested in all the different variations one can take at any given solve step. I've found myself following a similar pat

2017-03-01 Thread Robert Lee
Following up on this conversation, has anyone given any thought on an efficient way to check for structural equality for evaluate=False expressions? This is my current implementation but I'd be curious if there is a niftier way to check instead of manually recursing through like I've done: htt

Other algorithms that would be useful, if you believe you are capable of implementing them: - cylindrical algebraic decomposition (CAD) - the Risch algorithm. There are references on the ideas page. Both are challenging from a mathematical point of view (though I believe less so than Karr). Aar

Hi, Here is a project that I would love to see happen: https://github.com/sympy/sympy/issues/12233 I am available to mentor it, and I think quite a few people are excited about it and such a system/framework (i.e. set of rules for patter matching + compiler to generate a fast if/then/else decisi

I've been thinking about applying again, though I am not sure what the project should be. Are there any good algorithms that are not implemented that could make a good project (I've read the ideas page)? I have 3 projects in mind: (a). Implementation of Karr's algorithm, I believe no one has don
