2023 Victor Ciura | @ciura_victor - Regular, Revisited X Abstract “Regular” is not exactly a new concept. If we reflect back on STL and its design principles, as best described by Alexander Alexander Stepanov in his “Fundamentals of Generic Programming” paper, we see that regular types naturally appear as necessary foundational concepts in programming. Why do we need to bother with such taxonomies composite objects, ordering and equality. Designing and implementing regular types is crucial in everyday programming, not just library design. Properly constraining types and function prototypes will result

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 notation allows a more natural expression of the idea of an algorithm, replacing the clutter of variable pairs and a morass of explicit comparisons. Generic. The library handles the differences between

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++
