Abstract EN
There are many issues to consider when integrating 5G networks and the Internet of things to build a future smart city, such as how to schedule resources and how to reduce costs.
This has a lot to do with dynamic multiobjective optimization.
In order to deal with this kind of problem, it is necessary to design a good processing strategy.
Evolutionary algorithm can handle this problem well.
The prediction in the dynamic environment has been the very challenging work.
In the previous literature, the location and distribution of PF or PS are mostly predicted by the center point.
The center point generally refers to the center point of the population in the decision space.
However, the center point of the decision space cannot meet the needs of various problems.
In fact, there are many points with special meanings in objective space, such as ideal point and CTI.
In this paper, a hybrid prediction strategy carried through from both decision space and objective space (DOPS) is proposed to handle all kinds of optimization problems.
The prediction in decision space is based on the center point.
And the prediction in objective space is based on CTI.
In addition, for handling the problems with periodic changes, a kind of memory method is added.
Finally, to compensate for the inaccuracy of the prediction in particularly complex problems, a self-adaptive diversity maintenance method is adopted.
The proposed strategy was compared with other four state-of-the-art strategies on 13 classic dynamic multiobjective optimization problems (DMOPs).
The experimental results show that DOPS is effective in dynamic multiobjective optimization.
