feedback on litpton-tarjan separator
by Jeff Linahan 30 Mar '20

30 Mar '20

Hello BGL users, after 5 years I'm almost ready to start writing documentation for my lipton-tarjan planar separator algorithm and finally submit my first implementation for formal peer review for inclusion in BGL. But one last question I have is feedback on how people would like the public interface for how a function like this will work (especially the template part which I'm not as good at). The internals will be easier to change as I continue to develop the implementation. This is essentially what I have now: struct Partition { std::set<vertex_t> a, b, c; }; Partition lipton_tarjan_separator(boost::adjacency_list<boost::vecS, boost::vecS, boost::undirectedS, boost::property<boost::vertex_index_t, uint>, boost::property<boost::edge_index_t, uint>> const&); I'd like to make it more generic eventually, but is that good enough for inclusion in BGL as is? Full code here: https://github.com/jeffythedragonslayer/lipton-tarjan Thanks, Jeff

[GSoC 2020] Extraordinary circumstances and early birds
by madhur4127 29 Mar '20

29 Mar '20

Hi Boost Community, I am Madhur, an active contributor to Boost.Multiprecision. I am from India and am observing that summer internships (for students in the penultimate year) are being canceled because of COVID-19. This is a huge loss to brilliant and enthusiastic students as they will not be able to gain experience. This could be an opportunity for Boost to mentor these students who don't have prior experience with open source or with a rich C++ background. If a student is ready to devote himself/herself then I guess there's enough time to learn (till Jun 1) about C++/Project to get things rolling. > FYI, you are late. Mateusz posted in other thread about the student being late (as of today) but the GSoC application deadline is due March 31, which I would wholeheartedly agree in case of normal circumstances. The point I'm trying to make here is that in these extraordinary circumstances: - should Boost neglect the "early bird" and treat all applicants equally? - should Boost compensate for the lack of work samples with the history of the student (like academic records, academic projects, research papers)? - should Boost consider other factors too while selecting the student this year like the education level (seniority level: 4th/5th year of study or PhD)? For example, if a student had taken a course in numerical algorithms/computational algorithms then that applicant's insights could be beneficial to Boost.Multiprecision than other applicants. If a student performs well in the competency test then it indicates that the student would do the job and I think the selection criteria should be tweaked so as to consider that students who lost internships and otherwise who could be a great value to the library (even for a short time - GSoC) don't get neglected. Well, these are my views as a student. Eagerly waiting for your thoughts! Thank you for having time to read this unusually long message :) -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Dev-f2600599.html

[GSoC20] Seeking mentor
by Martin Carrasco Castaneda 29 Mar '20

29 Mar '20

Hello, I am seeking a mentor for the GSoC program for this year. I have some experience with DSP and just submitted a very basic PR with a filter implementation. I find this topic very interesting and have some general ideas for available mentors. I'd like to work in implementing features for deblurring such as the Weigner filter or the Least Square filtering. I am also interested in working in feature extraction filters such as the Hough transform or related subjects. I am pretty much open to any subject relating to GIL.

Regarding PCT (boost astronomy , coordinate transformation/conversion)
by GOPAL RAMESH DAHALE 28 Mar '20

28 Mar '20

I have written a class to transform cartesian_representation vector with the help of the affine matrix(3x3). My problem is that I am not able to work with boost::unit:: quantity. I work with the quantity values but later on not able to assign it to the resulting cartesian_represtentaion(res). Any help is appreciated. Thank You.

28 Mar '20

Dear I am thinking about make automatic test for boost, but with not supporting toolset yet. Is there any tutorial or template for b2: how to add new toolset support? I was looking documentation already, in my opinion no simply way due lack of kind of "easy tutorial". Best regards Grzegorz Konopko

by Tom Kwok 28 Mar '20

28 Mar '20

Hi everyone, May I know if there are any potential mentors for my Boost.uBlas data frames project proposal besides Mr. David Bellot? He has not been responding to messages lately. Not sure if it is because of the recent Covid-19 situation. Best regards, Tom
