[sympy] Re: GSoC 2019 Initial Project Proposal - Assumptions

I would like if mentors give suggestions about the course of action I should take and the improvements I should make in the proposal. The project is huge and for the past few days, I have been going to and from between core modules and assumptions module. I have some questions : - Why do

Re: [sympy] Gsoc Project idea " Efficient Equation ofMotionGenerationwith Python" discussion.

I agree. The biggest challenge with symbolic matrices is expression blow up. In some cases it is unavoidable, for instance, symbolic eigenvalues/eigenvectors use the symbolic solutions to polynomials, which are complicated in the general case for n > 2. One thing I meant by "overhead" is that if

@asmeurer Well group theory concept is quite different and is really worth implementing unlike karatsuba, ffts, or cook s algo etc. On Fri, Mar 15, 2019, 01:20 Aaron Meurer wrote: > For matrices in sympy, I suspect in most cases the best speed ups would > come from removing overhead from the

I haven't looked at SymPy's specific code for generating equations of motion but I have used SymPy for generating equations of motion and other mechanics related problems. The example here: https://github.com/sympy/sympy/issues/16207 comes from a mechanics problem and was slow because of slow

Re: [sympy] Gsoc Project idea " Efficient Equation ofMotionGenerationwith Python" discussion.

For matrices in sympy, I suspect in most cases the best speed ups would come from removing overhead from the calculations, rather than from algorithmic improvements. Many of the algorithms mentioned here are only theoretically faster, or only faster asymptoticly. In some cases, they would only be

Yes Kunal, this is where you should be asking the doubts, in gitter, there is a chance of the conversation being lost and also here it will be helpful to other people to add their viewpoints. Jogi, the plan looks good, go ahead with it, I will try to review and clear doubts as much as I can, I

Yes, I have studied group theory in my college curriculum. I tried to find ways by which group theory cap to used to simplify matrix multiplication and came across https://web.wpi.edu/Pubs/ETD/Available/etd-012318-234642/unrestricted/zli.pdf and

Hello Aaron, Thanks for clarifying. My most of the work is around Solvers module (but I am ready for any new things as well). I see that good amount of work is pending in SymEngine solvers and Ruby wrapper

Re: [sympy] Gsoc Project idea " Efficient Equation of MotionGeneration with Python" discussion.

Well if you see these algorithms are not for general purpose matrices but for where high accuracy is required. I would rather say to use concepts of group theory and representation theory (i do not have lot of knowledge about this but 'm studying) which can reduce matrices to lower dimensions.If

I am personally not convinced that Karatsuba, Coppersmith-Winograd and Strassen will provide much help here. Basically because only rarely, the size of the problem is the main issue. These algorithms show excellent asymptotic behaviour, but also has an overhead which leads to that quite large
