Let us start with two examples. A company has a machine which drills holes into printed
circuit boards. Since it produces many of these boards it wants the machine to complete one …

This paper seeks to describe several features of establishing a closed-loop supply chain for
the collection of End-of-Life Vehicles in Mexico. To address this task, the problem is handled …

The rapid growth of electronic commerce is having an impact on the way urban logistics are
organized. In metropolitan settings, the last-mile delivery problem, ie, the problem regarding …

Providing timely results in the face of rapid growth in data volumes has become important for
analytical frameworks. For this reason, frameworks increasingly operate on only a subset of …

This paper shows that one can be competitive with the k-means objective while operating
online. In this model, the algorithm receives vectors v 1,…, vn one by one in an arbitrary …

In many countries health system data remain too weak to accurately enumerate Plasmodium
falciparum malaria cases. In response, cartographic approaches have been developed that …

We obtain a 1.5-approximation algorithm for the metric uncapacitated facility location (UFL)
problem, which improves on the previously best known 1.52-approximation algorithm by …

Network virtualization provides a novel approach to running multiple concurrent virtual
networks over a common physical network infrastructure. From a research perspective, this …

Beginnen wir mit zwei Beispielen. Eine Firma betreibt eine Maschine, mit der Löcher in
Leiterplatten gebohrt werden. Da sie viele dieser Platinen herstellt, möchte sie erreichen …

We consider the metric uncapacitated facility location problem (UFL). In this paper we modify
the (1+ 2/e)-approximation algorithm of Chudak and Shmoys to obtain a new (1.6774 …
