Algorithm 2

Algorithm for handling MAED problem by grey wolf optimizer.
Step 1: assign grey wolf population Xk (k = 1, 2, …, N); N = no of generators
Step 2: initialize a, A, and C
Step 3: compute the objective function values for each search agent
Step 4: find all solutions and initializ the best solution with them
Step 5: Xα = select first leader (archive)
Xβ = select second leader (archive)
Xδ = select third leader (archive)
z = 1;
Step 6: while (z < Max iterations)
Step 7: for every variable
 Update position of present search solution by equations (8)–(13)
end for
Step 8: modernize a, A, and C
 Compute fitness values of every solution
 Then find other solutions
  Update the solution with reference to best solutions
Step 9: If particle checking is full
 Run the grid mechanism to omit one of the present archive members
 Add the new solution to the archive end if
Step 10: If any new added solutions to the best solution are located shell to a hypercube
 Update the population with other new solution(s) end if
Step 11: Xα = select leader (archive)
 Exclude alpha from the archive temporarily to avoid selecting the same leader
Xβ = select leader (archive)
 Exclude beta from the archive temporarily to avoid selecting the same leader
  Xδ = select leader (archive)
  Add back alpha and beta to the archive
  t = t + 1
  end while
Step 12: return archive
