Constraints Relaxation for the Discrete Ordered Median Problem

L. I. Martínez-Merino, D. Ponce, J. Puerto

Recently, the Discrete Ordered Median Problem (DOMP) has been formulated using set packing constraints to model the order. These constraints are also known as Strong Order Constraints (SOC). We propose a branch-and-cut procedure starting from a constraints relaxation of the DOMP. Particularly, we consider a constraints relaxation of the DOMP where SOC are not included and we add them iteratively using row generation techniques to certify feasibility and optimality. We present some computational results that compare this procedure with other formulations and solution techniques for the DOMP.

Keywords: Discrete Ordered Median Problem, Branch-and-Cut, Constraints relaxation, MILP.

    Visit Alhambra

    Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport. The document must be the same whose number matches the ticket number you have.
