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

Algorithm 4

Hybrid predictive strategy.

Input:  , the capacity of memory set; , the size of the population;

and , the population in t-1 and t time step.

Output: The final non-dominated set, and its size, .

Step 1: Layer the , and select the individuals in the first layer as the

non-dominated set, , and get its capacity, ;

Step 2: According to Algorithm 1, calculate the non-dominated set, ;

Step 3: According to Algorithm 2, calculate the non-dominated set, ;

Step 4: According to Algorithm 3, calculate the final non-dominated set, ,

and its size, ;
