A C++ library with R interface for practical volume computation and sampling of convex bodies in high dimensions.
VolEsti is a C++ library with an R interface for volume approximation and sampling of convex bodies, such as polytopes, in high-dimensional spaces. It solves complex computational geometry problems by providing efficient algorithms for volume computation and uniform sampling, which are essential in fields like statistics, optimization, and machine learning. The library is part of the GeomScale project, focusing on practical and scalable geometric computations.
Researchers, statisticians, and data scientists working with high-dimensional data, computational geometry, or optimization who need to compute volumes or generate samples from convex bodies. It is particularly useful for those using R for statistical analysis.
Developers choose VolEsti for its specialized algorithms that handle high-dimensional convex bodies efficiently, its seamless integration with R for ease of use, and its open-source nature under the GeomScale project, offering a robust alternative to proprietary computational geometry tools.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Built on C++ for efficient computation of geometric operations, ensuring scalability for high-dimensional problems as emphasized in the library's philosophy.
Offers a CRAN-published R package, making it easily accessible for statistical computing and visualization workflows, as shown by the CRAN status badge and download metrics.
Specializes in randomized algorithms for volume approximation and sampling of convex bodies, backed by publications and detailed tutorials on the GitHub wiki.
Demonstrates robust continuous integration with badges for gcc, clang tests, and regular updates, ensuring reliability and ongoing improvements through the GeomScale project.
Python interface is not native and requires a separate package (dingo), as admitted in the README, limiting its utility for Python-centric projects without additional setup.
Focused on high-dimensional spaces, computations can be memory and CPU intensive, making it unsuitable for resource-constrained environments or lightweight applications.
While the R package is easy to install, the underlying C++ library may require manual compilation and dependencies, indicated by the CMake-based build workflows and potential platform-specific issues.
