Mixed integer linear programming and heuristic methods for feature selection in clustering
(Taylor & Francis, 2018)
This paper studies the problem of selecting relevant features in clustering problems, out of a data set in which many features are useless, or masking. The data set comprises a set U of units, a set V of features, a set R ...

A discretization result for some optimization problems in framework spaces with polyhedral obstacles and the Manhattan metric
(Elsevier, 2018-07)
In this work we consider the shortest path problem and the single facility Weber location problem in any real space of finite dimension where there exist different types of polyhedral obstacles or forbidden regions. These ...
