Multiobjective Optimization Method for Polymer Injection Molding Based on a Genetic Algorithm

Algorithm 2

NonDominatedRank.

Input score //Enter the objective function value, the number of rows ‘popSize’ is the

number of populations after the merger, the number of columns is the value of the

objective function

do

for p=1 topopSize

 if pis Sorted

  continue // Perform the next cycle

end if

for q=1 to popSize

If there is a function value greater than p’s in q and all of q’s function values are not less

than p’s

q dominate p;

 end if

end for

if p is not dominated

Assigns the current rank to p and p is sorted

end if

end for

rank++;

while all individuals are sorted

Output rank //Output combined population order value
