Hello everyone! I'm trying to find an optimal placement for a recloser using the optimization toolbox. The best place to set a recloser is defined by minimal SAIFI (system average interruption frequency index) value. I've created a little function where Nt - total number of customers, G - are some weights characterizing power lines, Xi - number of interrupted customers (if interruption happens in i-th line AND it has a recloser in it), Mi - row of 1 and 0 (that genetic algorithm should use as a gene I guess...) Here's the code of function:

function [S] = SAIFI_sum (M)
Nt=270;
G = [1.1 1.2 1.3 1.4 1.5 1.6];
X = [270 30 220 180 60 70];
  for i=1:length(M)
      if  M(i)== 1
      N(i) = X(i);
  else
          N(i) = Nt;
      end
  end
  S = 0;
  for j=1:length(M)
      SAIFI(j) = N(j)*G(j);
      S = S + SAIFI(j);
  end
   S
end
As a result I have 51 same results: S = 297 and following message:
"Optimization running.
Objective function value: 297.0
Optimization terminated: average change in the fitness value less than options.FunctionTolerance".
I couldn't understand how to solve this problem.
