I am working on a problem which, from what I can tell from prior research, is troubling many people in the industry I work in. In civic engineering, particularly fibre-optic cables, house connections (HCs) need to be grouped into clusters hooked up to network distributors (NDs). Intuitively, one might assume this to be a problem for simple clustering algorithms such as kmeans, however, the issue arises with the infrastructure-imposed limit of 20 HCs per ND. If HCs are too dense in one area, kmeans etc. construct clusters exceeding such limitations.
