    This paper presents the p-next center problem, which aims to locate p out of n centers so as to minimize the maximum cost of allocating customers to backup centers. In this problem it is assumed that centers can fail and ...
  • Interior-point solver for convex separable block-angular problems 

    Castro Pérez, Jordi (2014)
    External research report
    Open Access
    Constraints matrices with block-angular structures are pervasive in Optimization. Interior-point methods have shown to be competitive for these structured problems by exploiting the linear algebra. One of these approaches ...
