exact-clustering 0.5.1

Find optimal clusterings and optimal hierarchical clusterings.

Low-effort way of calling the rust-crate exact-clustering from Python.

pip install exact-clustering

Consult docs.rs for more extensive documentation.

from exact_clustering import *

weighted_points = [
    (1.0, [0, 0]),
    (1.0, [1, 0]),
    (3.0, [0, 2]),
]

print(

        weighted_points
