    • An incremental exact algorithm for the hyper-rectangular clustering problem with axisparallel clusters 

      Delle Donne, Diego; Marenco, Javier; Moreno, Eduardo (Arxiv, 2024-10-15)
      We address the problem of clustering a set of points in Rd with axis-parallel clusters. Previous exact approaches to this problem are mostly based on integer programming formulations and can only solve to optimality ...

    • An integer programming approach for the hyper-rectangular clustering problem with axis-parallel clusters and outliers 

      Marenco, Javier (Universidad Torcuato Di Tella, 2023)
      We present a mixed integer programming formulation for the problem of clustering a set of points in Rd with axis-parallel clusters, while allowing to discard a pre-specified number of points, thus declared to be outliers. ...

    • Analysis of a generalized Linear Ordering Problem via integer programming 

      Vulcano, Gustavo; Mendez-Diaz, Isabel; Zabala, Paula (Discrete Applied Mathematics (e-ISSN: 1872-6771), 2019-12-01)
      We study a generalized version of the linear ordering problem: Given a collection of partial orders represented by directed trees with unique root and height one, where each tree is associated with a nonnegative reward, ...

    • Crime and violence: Desensitization in victims to watchingcriminal events 

      Di Tella, Rafael; Freira, Lucía; Gálvez, Ramiro; Schargrodsky, Ernesto; Shalom, Diego E.; Sigman, Mariano (Universidad Torcuato Di TellaJournal of Economic Behavior & Organization (e-ISSN: 1879-1751), 2019)
      We study desensitization to crime in a lab experiment by showing footage of criminal acts to a group of subjects, some of whom have been previously victimized. We measure biological markers of stress and behavioral indices ...

    • Demand Estimation under Uncertain Consideration Sets 

      Vulcano, Gustavo; Jagabathula, Srikanth; Mitrofanov, Dmitry (Operations Research (ISSN: 0030-364X), 2023-09)
      To estimate customer demand, choice models rely both on what the individuals do and do not purchase. A customer may not purchase a product because it was not offered but also because it was not considered. To account for ...

    • Electric Vehicle Routing Model for Last-mile Logistics in Cities with Steep Streets 

      García, Emilio; Torres, Luis M; Miranda Bront, Juan José (Memorias de las JAIIO (ISSN 2451-7496), 2024-08-29)
      The Quito local government aims to establish a low-emission zone in the city’s historic center. A key focus is the shift to eco-friendly transportation for last-mile logistics, including electric cargo bikes and other ...
