GSoC 2023 | GeomScale | IIT Kharagpur
Here’s a detailed overview of the progress achieved during the Google Summer of Code (GSoC) 2023, focusing on refining the Volesti R Package for GeomScale.
Throughout this venture, several key aspects of the project were thoroughly examined, including the strategic restructuring of the repository, the integration of comprehensive tests and optimization efforts to boost the package’s overall performance.

Overview: One of the principal objectives encompassed the establishment of a dedicated repository for the Volesti R Package, in light of the prior amalgamation of both R and C++ code within a singular repository, which subsequently posed organizational complexities. In response, a conscientious endeavor was undertaken to restructure the repository framework for the stable Volesti version 1.1.2-6. This endeavor involved the segregation of the R package code into a distinct repository denominated as Rvolesti, resulting in heightened lucidity and a more streamlined developmental approach.
In order to facilitate seamless cohesion between the Rvolesti and Volesti repositories, the implementation of Git Submodule was undertaken. This strategic step enabled the Rvolesti repository to seamlessly retrieve the requisite Header Files from the Volesti repository.
Integration of Comprehensive Tests:

Overview: Ensuring the dependability and resilience of the Volesti R Package necessitated the incorporation of thorough testing mechanisms. In pursuit of this goal, emphasis was placed on the implementation of CI tests through the utilization of GitHub Actions. Specifically, the rcmdcheck package was utilized to execute static analysis and validate the R package comprehensively.
Elimination of the Test Notes with .Rbuildignore:

Overview: During the CI testing phase, there were instances where unnecessary Notes were generated, posing a potential for ambiguity. In response, efforts were channeled towards the integration of the .Rbuildignore file into the Rvolesti repository. This file facilitated the exclusion of certain files or elements from the testing procedure.
Modification of the R Codes:

Overview: Upon the establishment of the initial framework, a requirement emerged to integrate the latest functionalities into Rvolesti. Subsequently, the process of replicating the R files from the develop branch of Volesti was initiated, leading to the assimilation of the following functions:
Deletion of C++ Modules:

Overview: To resolve the challenges posed by the CI tests post the assimilation of the latest code, distinct Class Files were incorporated into the R directory. The files, specifically HpolytopeClass.R, SpectrahedronClass.R, VpolytopeClass.R, VpolytopeIntersectionClass.R, and ZonotopeClass.R, had earlier been realized as a C++ module.
In addition to the tasks previously outlined, several other issues pertinent to both Volesti and Rvolesti were addressed. Notable among these were:
Modification of the cran_include Branch of Volesti

Restructuring the README.md in Rvolesti
PR Link: https://github.com/GeomScale/Rvolesti/pull/14
Lastly, it is important to note that Rvolesti is a newly established repository that may necessitate further refinement to attain full functionality. The prospect of contributing towards enhancing its functionality is an endeavor that holds a strong appeal and interest.
I extend my heartfelt gratitude to the GeomScale community for providing an enriching environment for development and growth. And the insights and expertise shared by my mentors, Apostolos Chalkis and Vissarion Fisikopoulos, have been instrumental in shaping this journey.
