In this paper, we present a framework of different interactive NAUTILUS
methods for multiobjective optimization. In interactive methods,
the decision maker iteratively sees solution alternatives and provides one’s
preferences in order to find the most preferred solution. We question the
widely used setting that the solutions shown to the decision maker should
all be Pareto optimal which implies that improvement in any objective
function necessitates allowing impairment in some others. Instead, in
NAUTILUS we enable the decision maker to make a free search without
having to trade-off by starting from an inferior solution and iteratively
approaching the Pareto optimal set by allowing all objective functions
to improve. The framework presented consists of different modules for
preference elicitation and optimization. Four main NAUTILUS method
variants are introduced as well as ideas of utilizing the framework in a
flexible way to derive further variants.
