kiwisolver: An implementation of the Cassowary constraint solving algorithm#
A fast implementation of the Cassowary constraint solver
Kiwi is an efficient C++ implementation of the Cassowary constraint solving algorithm. Kiwi is an implementation of the algorithm based on the seminal Cassowary paper. It is not a refactoring of the original C++ solver. Kiwi has been designed from the ground up to be lightweight and fast. Kiwi ranges from 10x to 500x faster than the original Cassowary solver with typical use cases gaining a 40x improvement. Memory savings are consistently > 5x.
In addition to the C++ solver, Kiwi ships with hand-rolled Python bindings.

Equivalent System Packages#
$ conda install kiwisolver
macports: install the following packages: py-kiwisolver
$ sudo xbps-install python3-kiwisolver
However, these system packages will not be used for building Sage because using Python site-packages is not supported by the Sage distribution; see trac ticket #29023
