kiwisolver: kiwisolver (an implementation of the Cassowary algorithm) kiwisolver: kiwisolver: This is an efficient C++ implementation of the Cassowary constraint kiwisolver: solving algorithm. Kiwi(solver) is an implementation of the algorithm kiwisolver: based on the seminal Cassowary paper. It is not a refactoring of the kiwisolver: original C++ solver. Kiwi(solver) has been designed from the ground kiwisolver: up to be lightweight and fast. kiwisolver: kiwisolver: Homepage: https://pypi.org/project/kiwisolver kiwisolver: kiwisolver:
