[sage-devel] Re: Parallelization of Boruvka's Algorithm

Sure. Since this is written in cython, using https://cython.readthedocs.io/en/latest/src/userguide/parallelism.html might be a good choice. This is also used in `src/sage/geometry/polyhedron/combinatorial_polyhedron/face_iterator.pyx`. Note the first two lines of the file. With those lines, yo

[sage-devel] Reviving the Annual SageMath Development Prize

Hi sage-devel, We (Matthias Koeppe and William Stein) would like to propose that we revive the Annual SageMath Development Prize, which was awarded in the years 2008–2014 thanks to donations from Jaap Spies (a retired Dutch mathematician) – see https://www.sagemath.org/development-prize.html To

Cython files are now discovered automatically. There is no need to add the name of the pyx file anywhere. On Tuesday, April 12, 2022 at 10:21:44 AM UTC-7 adarsh.k...@gmail.com wrote: > Ok, then in the new version of Sage what is the equivalent file I should > look? > > On Tuesday, April 12, 20

[sage-devel] Re: Sage does wrong vector comparison when using assume

Thanks for reporting the bug. The problem comes from the fact that `if lhs != rhs:` is not the same as `if not(lhs == rhs):` when `lhs` and `rhs` are in `SR`, and the test for equality of vectors uses the wrong one. I opened trac ticket #33697 to fix this

[sage-devel] Re: Kruskal's Algorithm using Priority Queues

Just wondering if the third TODO (Randomized spanning tree construction) should be removed as well, since I see a function called "random_spanning_tree" exists already. On Monday, April 11, 2022 at 8:23:30 AM UTC+1 adarsh.k...@gmail.com wrote: > Okay, then I think that line should be removed rig

Re: [sage-devel] Plotting kills Sagemath in ubuntu (plot(f(x),1,-1))

Most probably, you're running a binary installation of Sage (what version?) on a CPU that does not match CPUs your binary was built for. On Mon, Apr 11, 2022 at 11:42 PM Eliton Trindade Gomes wrote: > > return error > > > /

[sage-devel] divmod() vs .quo_rem()

Python defines divmod() and the associated .__divmod__() magic method for what Sage calls .quo_rem(). Is there any reason why Sage shouldn't or cannot support divmod()? -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To unsubscribe from this gr
