WebMay 11, 2024 · The main work of clustering is converting a group of abstract or different objects into similar objects. It is also used for separating the data or objects into a set of data or objects which finally gets into a group of subclass called a cluster. Various data objects in a cluster are considered as one single group. WebMay 3, 2024 · When there are constraints on the size of clusters, the problem is (informally) known as the balanced clustering problem or capacitated clustering problem. The Wikipedia article does contain a few links of its implementation.
