The minimum-sum-of-squared error clustering (MSSC) is one of the most intuitive and popular clustering algorithms. In this paper, we first show that MSSC can be equivalently cast as a concave minimization prob-lem. To find the global solution of MSSC, we construct a procedure to move from a fractional solution of the relaxed minimization problem to an integer solution with improved objective value. Then we adapt Tuy’s convexity cut method, a powerful algorithm for global concave optimiza-tion, to find a global optimum to MSSC. Promising numerical examples are reported.
