Researchers from the Intelligent Systems Group of the University of the Basque Country (UPV/EHU) and the Technical University of Madrid (UPM) have developed several theoretical concepts of Estimation of Distribution Algorithms (EDAs), as well as a program which implements EDAs and some more appeared in the literature. This concrete web page addresses the application of EDAs to the Table Ordering Problem: given the information of a 2D table, it optimizes the arrangement of rows and column to return a table easier to interpret. The authors of the study are Endika Bengoetxea from UPV/EHU, and Pedro Larrañaga, Concha Bielza and Juan Antonio Sánchez Pozo from the UPM. The next is a program which applies by default the best parameters for this problem accoording to our research: Windows NT/2000/XP version: CEDA-OrderingOfTables.exe To run it, from the Start->execute option, type cmd; from it, type: CEDA-OrderingOfTables and you will have on the screen the whole list of parameters and options accepted by the program. For instance, a typical execution, with UMDA, would be started in the following way: CEDA-OrderingOfTables -l0 -o out.dat which would leave the results in the file out.dat, although these will also appear on the screen.
