On the exponential cardinality of FDS for the ordered p-median problem [Article]
We study finite dominating sets (FDS) for the ordered median problem. This kind of problems allows to deal simultaneously with a large number of models. We show that there is no valid polynomial size FDS for the general ...
A generalized model of equality measures in network location problems [Article]
In this paper, the concept of the ordered weighted averaging operator is applied to define a model which unifies and generalizes several inequality measures. For a location x, the value of the new objective function is the ...
Sum-of-squares clustering on networks [Article]
(University of Belgrade, 2011)
Finding p prototypes by minimizing the sum of the squared distances from a set of points to its closest prototype is a well-studied problem in clustering, data analysis and continuous location. In this note, this very ...
