"WebOne of the fundamental clustering problems is to assign n points into k clusters based on minimal sum‐of‐squared distances (MSSC), which is known to be NP‐hard. In this paper, by using matrix arguments, we first model MSSC as a so‐called 0‐1 semidefinite programming (SDP) problem. We show that our 0‐1 SDP model provides a unified framework for … " - Cluster analysis and mathematical programming
