Hi @/all we would like to share some news on our new package called dingo
@TolisChal and @hariszaf did some great and hard work building that python package that can be use to analyse metabolic networks.
Even this is related to systems biology / bioinformatics topics we would like to as for the help of our community to try this package which is available here: https://github.com/GeomScale/dingo
There are also some good first issues here https://github.com/GeomScale/dingo/issues if feel like contributing to a new, fresh open source project.
Vissarion Fisikopoulos
@vissarion
We are happy to participate to Hacktoberfest (https://hacktoberfest.digitalocean.com) as GeomScale community.
We have labeled a few issues in our two main repositories: volesti and dingo
We are looking forward to your contributions. Also, if you have any ideas about new issues that could be suitable for this event (i.e. self-contained and simple for new comers) please let us know!

Hi everyone, I have created an issue for Codecov's Gtihub app integration with Geomscale so that every PR receives comments related to coverage changes. If anyone has previous experience with Codecov, feel free to add more context here on this issue: GeomScale/volesti#191.
Vissarion Fisikopoulos
@vissarion
Thanks @vaithak for adding this issue. It is addressed so now volesti will let the contributor know whether their PR increases or decreases the coverage. Useful utility indeed!

Hello! Cooling ball implemented in volesti seems like an efficient algorithm for volume computation. But I fail to find any documentation or publication detailing it. I only found cooling gaussian while I believe they are different. Is there any reference for me to get more information about this algorithm? Thank you.
Vissarion Fisikopoulos
@vissarion
@MeadowsZh_gitlab indeed "cooling balls" is different than "cooling gaussians". The algorithm is described in detail in https://arxiv.org/abs/1905.05494
Documentation of the code is not written yet, unfortunately.

Hello everyone, I my name is Rahul Kumar and I really like to contribute to the community. I visited https://github.com/GeomScale/volesti/blob/develop/CONTRIBUTING.md yesterday and trying to set up working , as shown here "To compile the C++ code you have to specify the path to external library liblpsolve55.so/dll/dylib" . I have been trying to install liblpsolve55 but I am having trouble installing, So I was wondering if can setup environment in Visual Studio Code or Anaconda?

Hello, Pratham Shah here, an undergrad at VJTI, Mumbai. I would like to contribute to volesti. I looked into GeomScale/volesti#193 issue and while reproducing it on my system, I got an error in cmake of examples/vpolytope-volume. I think there is a typing error in CMakelist on line no. 109 and 110, it should be vpolytopevolume.cpp not vpolytopeVolume.cpp.

Hello everyone, I'm Partha Pratim Deka. I am more of a learner than a coder. I have good knowledge of python, jupyter notebook, C++, and a few web-d related languages. I am presently learning ML stuff. I will try to contribute to Geomscale as much as possible. My present target would be to contribute at least 3 times a week. I hope that I will be able to learn a lot by contributing to this organization and community.

Hi
Can anyone tell me what concepts are required to understand the codebase of volesti
I mean which algorithms or concepts other than basic programming
Vissarion Fisikopoulos
@vissarion
Basics of convex geometry, probability theory, linear algebra and algorithms should be enough.
The mathematical background behind volesti is described in research papers here: https://geomscale.github.io/publications/ (the talks could be more accessible to start with https://geomscale.github.io/talks )

GeomScale organization has been accepted as a mentoring organization for the 2022 Google Summer of Code 🎉.

We propose several topics for software development internships with a strong algorithmic and mathematical flavor.
We are searching for contributors with strong programming skills in C++ and/or Python/R and solid background in at least one of the following topics: (randomized) algorithms, computational geometry, statistics, optimization. Stipends are paid by Google and interns can work from anywhere in the world.

NEW this year There are two types of projects: part time (~175 hours) or full time (~350 hours). Moreover, everybody can apply, no need to be enrolled as a student.

If interested check out our project page and get in touch with mentors now!

Hello Everyone! According to the projects displayed in the wiki, I am interested in these projects for gsoc 2022 https://github.com/GeomScale/gsoc2022/wiki/Exclude-Lpsolve-from-R-interface-of-volesti and https://github.com/GeomScale/gsoc2022/wiki/NUTS-for-Truncated-Hamiltonian-Monte-Carlo . I have tried solving the easy tests given below the projects. Now i would like to discuss and get started with the projects,So can someone help me regarding how to get started with the projects and what is the mode of communication to contact the mentors?
Thanks and your support will be highly appreciated.

Hey everyone! I am Akshat Jain sophomore at NSUT. Happy to join the GeomScale community and learn from others' experiences and share my learnings with the community. As I have made GUI in Qt using Cpp for NASA's rocket launch, I would love to work on the project "Sampling correlation matrices" while getting the inputs from mentors. Any leads would be really helpful. Thank you

Hi all, I'm trying to solve 'Randomized solver for Semidefinite Programs' test2. Any hint on how to use HnR algorithm to sample from the boundary of the spectrahedron? Thank you!

Hi everyone, I am Huu Phuoc Le at Sorbonne University and I would like to work on Sampling correlation matrices project. I did the tests 1 and 2 and want to ask some questions on Test 3: Use the generator (of LMI of the spectrahedron of correlation matrices) from Test 2 and the existing C++ spectrahedron class in volesti to sample uniformly distributed correlation matrices with Billiard Walk.

After creating the required spectrahedron, I launch RandomPointGenerator::apply through

Generator::apply(spectra, q, num_points, walk_len, randPoints, push_back_policy, rng);

and got an error 'no matching function for call to Spectrahedron<>::line_positive_intersect(Point, Point, VT, VT, NT)'. Looking through the source code, I found that BilliardWalk was written for polytopes but the function line_positive_intersect(Point, Point, VT, VT, NT) does not exist for Spectrahedron class. I would like to ask if the BilliardWalk for Spectrahedron exists already in volesti or the test asks to implemenent this functionality.

Looking forward to your answer.

Hi, I guess that all contributors that preparing to apply for GSoC 2022 are preparing their applications. This is a kind reminder that the deadline is approaching!
Please submit before 19 April otherwise your application will not be considered (details on gsoc website https://summerofcode.withgoogle.com/programs/2022).
Also please share the proposal drafts with your mentors to get some feedback ASAP.
Good luck to everyone!!!
