The development of an application based on a set of best software engineering practices involves first their selection. This process may become complex due to the variables involved. This paper presents an Operations Research approach for the selection of best software engineering practices for the development of applications or computational systems considering a series of alternatives and sel...

In this paper, we describe how to construct physical computer network topologies which can support the establishment of overlays that reduce or increase the distances between nodes. Reducing pairwise distances (i.e., compression) implies that the overlay enjoys significantly lower inter-node latencies compared to the ambient physical network; such an overlay can be used to implement a “high-per...

In this paper we extend the principle of proportional representation to rankings. We consider the setting where alternatives need to be ranked based on approval preferences. In this setting, proportional representation requires that cohesive groups of voters are represented proportionally in each initial segment of the ranking. Proportional rankings are desirable in situations where initial seg...

In this paper we introduce a new ranking algorithm, called Collaborative Judgement (CJ), that takes into account peer opinions of agents and/or humans on objects (e.g. products, exams, papers) as well as peer judgements over those opinions. The combination of these two types of information has not been studied in previous work in order to produce object rankings. Here we apply Collaborative Jud...
