Objective trade-off rate information in interactive multiobjective optimization methods: a survey of theory and applications
Petri Eskelinen · Aaltodoc (Aalto University) · 2008
In this paper we survey interactive multiobjective optimization methods that utilize, in a way or another, so called objective trade-off rate information.Objective trade-off information can be obtained by studying only the properties of the underlying multiobjective optimization problem.In the context of multiobjective methodology trade-off information can be useful because it can be used to indicate relative changes in values of other objectives when the value of some objective is altered from its current value.This kind of information is especially useful when supporting a decision maker.We analyze interactive methods that utilize the trade-off information and discuss some main benefits and drawbacks that can be related to trade-offs in general.As a conclusion we can see that in interactive methods objective trade-off information can be utilized at very different levels ranging from learning to decision making.
