The convergence of the Weiszfeld algorithm. (English) Zbl 0978.90066

Summary: We investigate the convergence properties of the Weiszfeld procedure when it is applied to the approximated \(\ell_p\)-norm single-facility location problem where \(p>2\). We show that convergence for \(p>2\) can be obtained by introducing a step size factor to the iterative procedure. Some numerical test results are also given.
