Kurzfassung
Optimizing several objectives that are often at odds with
each other provides di�cult challenges that are not encountered if having only one goal at hand. One intuitive way to solve a multi-objective problem is to aggregate the objectives and reformulate it as an optimization problem having just a single goal. This goal can be a designer speci�c aggregation of the objectives or a characterization of knees, trade-o�ffs, utilities, stronger optimality concepts or preferences.
This paper examines the theoretical relationships between two knee concepts and aggregate objective functions methods. The changes in the �tness landscape by utilizing different aggregations is also discussed.
