      Characterising the rankings produced by combinatorial optimisation problems and finding their intersections. 

      Hernando Rodríguez, Leticia ORCID; Mendiburu Alberro, Alexander; Lozano Alonso, José Antonio (Association for Computing Machinery, 2019-07)
      [EN] The aim of this paper is to introduce the concept of intersection between combinatorial optimisation problems. We take into account that most algorithms, in their machinery, do not consider the exact objective function ...

      Multi-GGS-groups have the congruence subgroup property 

      Garrido, Alejandra; Uria Albizuri, Jone (Cambridge University Press, 2019-02-21)
      We generalize the result about the congruence subgroup property for GGS-groups to the family of multi-GGS-groups; that is, all multi-GGS-groups except the one defined by the constant vector have the congruence subgroup ...
