Although a variety of coevolutionary methods have been explored over the years, it has only been recently that a general architecture for cooperative coevolution has been proposed. Since that time, the flexibility and success of this cooperative coevolutionary architecture (CCA) has been shown in an array of different kinds of problems. However, many(More)
Cooperative coevolutionary algorithms (CCEAs) have been applied to many optimization problems with varied success. Recent empirical studies have shown that choices surrounding methods of collaboration may have a strong impact on the success of the algorithm. Moreover, certain properties of the problem landscape, such as variable interaction, greatly(More)
The task of understanding coevolutionary algorithms is a very difficult one. These algorithms search landscapes which are in some sense adaptive. As a result, the dynamical behaviors of coevolutionary systems can frequently be even more complex than traditional evolutionary algorithms (EAs). Moreover, traditional EA theory tells us little about(More)
Though coevolutionary algorithms are currently used for optimization purposes, practitioners are often plagued with difficulties due to the fact that such systems frequently behave in counter intuitive ways that are not well understood. This paper seeks to extend work which uses evolutionary game theory (EGT) as a form of dynamical systems modeling of(More)
There are several errors in the paper titled An Empirical Analysis of Collaboration Methods in Cooperative Coevolutionary Algorithms appearing in the GECCO 2001 proceedings. The mistakes were regarding the number of evaluations performed for various experiments. The mistakes affect the results of the paper somewhat, and the conclusions minimally. In several(More)
