Algorithm 1: Mutation Strategies

Input: population size N, initialization population P, Neighborhood size k Output: population POP

Evaluate P Calculation of individual CD

for i=1: N

Select k individuals neighboring i Mpopulation=k individuals in decision space Npopulation=k individuals in objective space Select individuals randomly from M and N i1 by M, i2 by N, and i3 by P according to Eqs. (5) and (6) POP=POP∪i1∪i 2∪i3 end if
