A Hybrid Predictive Strategy Carried through Simultaneously from Decision Space and Objective Space for Evolutionary Dynamic Multiobjective Optimization

Table 3

Mean and Standard Deviation of MIGD values of five strategies on F5-F10. The values in bold face denote having the best effect in these five strategies. and indicate that DOPS is significantly better than and is equivalent to the corresponding strategy, respectively.
