analytic-combinatorics
A SageMath package with algorithms for analytic combinatorics in several variables.
A simple, time-tested, family of random hash functions in Python, based on CRC32 and xxHash, affine transformations, and the Mersenne Twister. 🎲
Reluctant walks tend to exit the quarter-plane in which they are constrained (because of strong negative drift), but this work shows how to randomly sample large reluctant walks anyway. (Lumbroso, Mishna, Ponty, 2017)
Lightweight library to parse combstruct grammars, and standalone tool to convert them to JSON.
