The first thing that needs to be performed when attempting to solve a task by means of cooperative coevolution is the division of the problem into several components that can be separately handled. When a potential solution for each component is evaluated, it is connected to those of the other complementary components for the purpose of building a complete solution. Similarly, in the end of the algorithm, complete results of the task are formed by gathering solutions for each of the components. A complete solution for a classification problem may consist of a set of rules. Consequently, in the novel approach of cooperative coevolutionary classification, each population evolves one type of rule. Experiments are driven on three data sets and obtained results demonstrate the promise of proposed technique.
