Note to self: Try out suggested fix [here](https://github.com/pysal/libpysal/blob/284d2ae3d8d2084e6c74901d79cc0e13029c6cce/libpysal/cg/rtree.py#L940) in `/libpysal/cg/rtree.py`.

@vinkolar @badwolf259 Do you have a reproducible example that generates silhouettes for two clusters are exactly the same?

It actually seems that `rtree` isn't even used in `spopt`. Closing for now. We can reopen if I am missing something.

@knaaptime @sjsrey Is this still under consideration / discussion? If so, I am going to move it over into *Discussions*.

OK, Let's go ahead and close for now. We can reopen in the future if the come up again.

@Shruthi-Patil Do you still have any interest in seeing this move forward in #188? If not, we'll go ahead and close it out.

@ljwolf Shall we go ahead and close this out as stale?

The OP [went in another direction](https://github.com/pysal/spopt/issues/187#issuecomment-1288487713) for a solution, so let's close.

[`pulp` now supports HiGHS](https://coin-or.github.io/pulp/technical/solvers.html#pulp.apis.HiGHS_CMD). So now we can easily implement that solver in a demo/example. And *if* we decide to support our MIPs through `scipy.optimize` with HiGHS later, it will...

I have have successfully installed HiGHS and used from the `pulp` interface. The demo runs will be in the `facloc_real-world_*` notebooks and added in #300.
