Solving Regularized Multifacility Location Problems with Unknown Number of Centers via Difference-of-Convex Optimization
W. Geremew, V. S. T. Long, N. M. Nam +1
In this paper, we develop optimization methods for a new model of multifacility location problems defined by a Minkowski gauge with Laplace-type regularization terms. The model is…

Nesterov's Smoothing Technique and Minimizing Differences of Convex Functions for Hierarchical Clustering
Nguyen Mau Nam, Wondi Geremew, Sam Raynolds +1
A bilevel hierarchical clustering model is commonly used in designing optimal multicast networks. In this paper, we consider two different formulations of the bilevel hierarchical…
