This directory contains all the necessary files for running the DECC-DML algorithm which is a cooperative co-evolutionary algorithm that uses differential grouping for forming the subcomponents of the co-evolutionary framework. This program is tested with the CEC'2010 and is based on the following research paper: ----------- References: ----------- DECC-D and DECC-DML algorithms: Omidvar, M., Li, X. and Yao, X. (2010), "Cooperative Co-evolution with Delta Grouping for Large Scale Non-separable Function Optimization", in Proceedings of Congress of Evolutionary Computation (CEC 2010), IEEE, p.1762 - 1769.

This function called from decc.m - README : this readme file. - result : the experimental results are stored in this directory. The recorded statistics are best of all runs, mean, and standard deviation. - runcompe.m : sets the search domain for different functions. - run.m : this file can be used to run the DECC-DML algorithm. - sansde.m : the subcomponent optimizer based on SaNSDE. - trace : this directory contains the intermediate results which can be used for drawing convergence plots and further analysis. - gsize : this directory is used to keep track of how the subcomponent size changes in each co-evolutionary cycle. It can be used to analyze the behavior of DECC-DML. -------- License: -------- This program is to be used under the terms of the GNU General Public License (http://www.gnu.org/copyleft/gpl.html).
