DESDEO : An Open Framework for Interactive Multiobjective Optimization

We introduce a framework for interactive multiobjective optimization methods called DESDEO released under an open source license. With the framework, we want to make interactive methods easily accessible to be applied in solving real-world problems. The framework follows an object-oriented software design paradigm, where functionalities have been divided to modular, self-contained components. The framework contains implementations of some interactive methods, but also components which can be utilized to implement more interactive methods and, thus, increase the applicability of the framework. To demonstrate how the framework can be used, we consider an example problem where the pollution of a river is controlled. To solve this problem with four objectives, we apply two interactive methods called NAUTILUS and NIMBUS and show how the method can be switched during the solution process.peerReviewe
