wasserplan 0.1.3

1-Wasserstein distances between districting plans

wasserplan is a library for computing 1-Wasserstein distances between GerryChain partitions.

Dependencies

wasserplan depends on GerryChain and CVXPY. We recommend installing these dependencies with Anaconda (see the official GerryChain installation instructions).

Using

We principally use this library to compute pairwise transport distances which we (approximately) project into 2D Euclidean space. A simple demonstration of this use case using Virginia congressional districts is available as a notebook (open in Colab).

Performance

By default, wasserplan uses the open-source, lightweight ECOS solver, which is included with CVXPY. However, this solver may exhibit performance issues for large graphs (thousands of nodes). Performance can be improved by using a commercial solver such as MOSEK.
