  • 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 ...

    Open Access
    Wind power generation has a key role in Spanish electricity system since it is a native source of energy that could help Spain to reduce its dependency on the exterior for the production of electricity. Apart from the ...
  • Bartering integer commodities with exogenous prices 

    Nasini, Stefano; Castro Pérez, Jordi; Fonseca Casas, Pau (2013-11)
    External research report
    Open Access
    The analysis of markets with indivisible goods and xed exogenous prices has played an important role in economic models, especially in relation to wage rigidity and unemployment. This paper provides a novel mathematical ...

    Castro Pérez, Jordi; Nasini, Stefano (2013-07)
    External research report
    Open Access
    Network analysis is of great interest for the study of social , biological and technolog- ical networks, with applications, among others, in busines s, marketing, epidemiology and telecommunications. Researchers are ...
  • A fix-and-relax heuristic for controlled tabular adjustment 

    Baena, Daniel; Castro Pérez, Jordi (2013-07)
    External research report
    Open Access
    Controlled tabular adjustment (CTA) is an emerging protect ion technique for tabular data pro- tection. CTA formulates a mixed integer linear programming problem, which is tough for tables of moderate size. Finding a ...
