Multiobjectivisation of the Antenna Positioning Problem

摘要

Multiobjectivisation is a technique which transforms a mono-objective optimisation problem into a multi-objective one with the aim of avoiding stagna-tion. The transformation can be performed by the addition of artificial objectives or by the decomposition of the original objective function. Several well-known multi-objectivisation schemes, based on the addition of artificial objectives, are analysed. Also, some novel artificial objectives are suggested. The main advantages of these multiobjectivisation methods are their generality and ease of implementation. Dif-ferent multiobjectivisation schemes have been applied to the mono-objective version of the Antenna Positioning Problem. Tests have been performed using NSGA-II, one of the most successful MOEAs. The experimental evaluation demonstrates that high quality results can be achieved by multiobjectivisation, when they are compared to the results obtained by the best mono-objective approaches.
