How can I override the AccuracyGoal parameter in NMinimize? Instead of the evaluation stopping at the required Accuracy, I want it to stop after a specific number of iterations, even if the AccuracyGoal is not reached. I tried the following example code, but it doesn't stop after 100 iterations.

NMaximize[{Norm[Array[c1, 10], Infinity]+Norm[Array[d1, 10], Infinity], 
   And @@ Table[-1 <= c1[i] <= 1, {i, 1,10}] && And @@ Table[-1 <= d1[i] <= 1, {i, 1, 10}]}, 
  Flatten[{Array[c1, 10], Array[d1, 10]}],Method -> "SimulatedAnnealing",MaxIterations -> 100];

This question is similar to my query, but is yet to be answered.

  • $\begingroup$ There is a typo in Table[-1 <= d1[i] <= 1, {i, 1, d10}] , change d10 to 10 and your code runs.! $\endgroup$

  • $\begingroup$ Yes, the code runs, but it doesn't stop after 100 iterations. $\endgroup$

  • $\begingroup$ That means NMaxmize doesn't need 100 iterations to find the solution! $\endgroup$

  • $\begingroup$ Yes for this particular toy example. But for a much more complex problem, I would like to stop the evaluation after say N iterations. $\endgroup$
