Summery of today's call discussion with Amit :
1. Confirming the idea to get integer solution using solveset, need to check domain= S.Integer . Call the diophantine methods (mostly need diop_solve method), this will return solution in terms of t0 . Now we can convert the solution tuple into Finiteset and return. 2. Similarly we can use solve_poly_system and bivariate.py methods for multivariate and transcendental equation solver . Extend the solveset to get solution for more than one symbols. 3. For simplified general solution of trigonometric equation need more discussion, https://github.com/sympy/sympy/pull/10898 and another idea that is : The number of `exp` terms more than number of solution will be more (union). If somehow we make single exp term then only one imageset that may give overall solution, that is general form. -- Shekhar Prasad Rajak On Thursday, 4 February 2016 00:40:34 UTC+5:30, Shekhar Prasad Rajak wrote: > > > Hello, > my name is Shekhar Prasad Rajak.I want to discuss about Solver and > Solveset module > https://github.com/sympy/sympy/wiki/GSoC-2016-Ideas#solvers .I am going > to apply for GSoc'16, so trying to know > what sympy community expecting. > Solveset came to Replace all internal solve() calls > https://github.com/sympy/sympy/issues/8711 > So I should focus on Solveset,right? > I have some questions : > 1.What are the main problems/issues in Solver and Solveset right now? > 2.Is Solveset module done?If not,what are the main features, that should > be added ? > I have seen Harsh's PR : https://github.com/sympy/sympy/pull/7523 > It seems, these need some works : > -functions solvable by LambertW > -functions that can be recast as polynomials with a change of variables > this, for example; this can be > factored out of solve where multiple generators are handled > -use something like this : > https://github.com/sympy/sympy/pull/7523#issuecomment-62198981 > to handle the XFAILed test test_real_imag_splitting1, this will be > handled in the set module. > > 3.This is list of Issues/ Discussions I found. > > https://github.com/sympy/sympy/wiki/GSoC-2014-Application-Harsh-Gupta:-Solvers#relevant-issues-discussions-and-references > > <https://github.com/sympy/sympy/wiki/GSoC-2014-Application-Harsh-Gupta:-Solvers#relevant-issues-discussions-and-references> > but I don't know, whether they are solved or not. > Issues which are still open in github repo, need solutions. > There are also links of pdf and research papers, I am not sure whether > they are implemented or not. > > 4.Can we use python library multiprocessing,Synchronization for the faster > execution?one issue was opened for the same,which is closed now.But it is > always better to take less time. > > > -- > Shekhar Prasad Rajak > > -- You received this message because you are subscribed to the Google Groups "sympy" group.
