  • An inside analysis of a genetic-programming based optimizer 

    Muntés Mulero, Víctor; Aguilar Saborit, Josep; Larriba Pey, Josep; Zuzarte, Calisto; Markl, Volker (Institute of Electrical and Electronics Engineers, 2006)
    Conference report
    Open Access
    The use of evolutionary algorithms has been proposed as a powerful random search strategy to solve the join order problem. Specifically, genetic programming used in query optimization has been proposed as an alternative ...
  • Hybrid in-memory and on-disk tables for speeding-up table accesses 

    Guisado Gámez, Joan; Wolski, Antoni; Zuzarte, Calisto; Larriba Pey, Josep; Muntés Mulero, Víctor (Springer, 2010)
    Conference report
    Open Access
    Main memory database management systems have become essential for response-time-bounded applications, such as those in telecommunications systems or Internet, where users frequently access a table in order to get information ...
  • Hybrid tables for speeding-up data accesses in hybrid database management systems 

    Guisado Gámez, Joan; Wolski, Antoni; Zuzarte, Calisto; Larriba Pey, Josep; Muntés Mulero, Víctor (2011)

  • Intensive crossovers: Improving quality in a genetic query optimizer 

    Muntés Mulero, Víctor; Aguilar Saborit, Josep; Zuzarte, Calisto; Larriba Pey, Josep (International Centre for Numerical Methods in Engineering (CIMNE), 2006)
    Conference report
    Open Access
    Database schemas and user queries are continuously growing with the need for storing and accessing large amounts of structured information. Among the several proposals to deal with Large Join Query Problem, genetic optimizers ...
