Currently, novelty_threshold is set to a fixed value in ProximityArchive. However, it would be nice if it could decrease over time, as this seems to be a common trick that enables continuing to add solutions to the archive when we can no longer find solutions that are sufficiently novel. One idea that makes sense is to add a coefficient, and every time the archive does not add enough solutions for X iterations, we can reduce the threshold by that coefficient. This way, solutions continue to be added to the archive.
