A mathematical programming approach to SVM-based classification with label noise
(ScienceDirect, 2022-08-30)
In this paper we propose novel methodologies to optimally construct Support Vector Machine-based classifiers that take into account that label noise occur in the training sample. We propose different alternatives based on ...

A Branch-Price-and-Cut Procedure for the Discrete Ordered Median Problem
(informs, 2020-01-07)
The discrete ordered median problem (DOMP) is formulated as a set-partitioning problem using an exponential number of variables. Each variable corresponds to a set of demand points allocated to the same facility with the ...

Network flow based approaches for the pipelines routing problem in naval design
(Elsevier, 2022)
In this paper we propose a general methodology for the optimal automatic routing of spatial pipelines motivated by a recent collaboration with Ghenova, a leading Naval Engineering company. We provide a minimum cost ...

A combinatorial optimization approach to scenario filtering in portfolio selection
(Elsevier, 2022-02-05)
Recent studies stressed the fact that covariance matrices computed from empirical financial time series appear to contain a high amount of noise. This makes the classical Markowitz Mean–Variance Optimization model unable ...

Routing for unmanned aerial vehicles: Touring dimensional sets
(Elsevier, 2021-07-09)
In this paper we deal with an extension of the crossing postman problem to design routes that have to visit different shapes of dimensional elements rather than edges. This problem models the design of routes of drones or ...

Unitary Owen Points in Cooperative Lot-Sizing Models with Backlogging
(MDPI, 2021-04-15)
This paper analyzes cost sharing in uncapacitated lot-sizing models with backlogging and heterogeneous costs. It is assumed that several firms participate in a consortium aiming at satisfying their demand over the planning ...
