stdx::interval, a library for intervals on totally ordered sets Eric Hughes, Meadhbh Hamrick stdx::interval, a library for intervals on totally ordered sets Eric Hughes, Meadhbh Hamrick In brief stdx::interval mathematical sense of an interval on a totally ordered set. The library reasons about intervals as sets, not as interval expressions. The library is header-only and targets C++20. It is available under the algorithm, replacing the clutter of variable pairs and a morass of explicit comparisons. Generic. The library handles the differences between discrete (e.g. int and other integral types) and continuous (string

Thanks engine – Jobs. Specifically, based on C++ coroutine which we shipped in C++ 20, without standard library support. I because the contents are pretty connected, so I will take all questions at the end but

micrograd++: A 500 line C++ Machine Learning Library Gautam Sharma Independent Researcher gautamsharma2813@gmail.com Abstract—micrograd++ is a pure C++ machine learning li- brary inspired by Andrej Karpathy’s Karpathy’s Python implementation of micrograd. This header only library aims to provide a simple yet powerful framework for building and training machine learning models. By leveraging the performance scares practitioners to adopt a C++ based machine learning library for prototyping. Python remains the first choice in that front. This library changes that by providing: • Modern C++ features: micrograd++
