Parallel Evolutionary Algorithms for Optimizing Data{based Generated Fuzzy Systems

Abstract. In the eld of data{based fuzzy modeling, the complexity of applications and the amount of data to be processed have grown continuously. Thus, the computational eort for solving these applications has also increased drastically. In order to meet this challenge, parallel computing approaches are applied. The task here is the optimization of data{based generated fuzzy rule bases. For this kind of application the tness evaluation of an individual is very time consuming. Here, a parallel genetic algorithm is applied to solve the optimization problem in an acceptable amount of time. Furthermore, it will be analyzed how the quality of the results changes with the use of multi{population models or neighborhood models. This will be illustrated by two example applications
