Q. How to get the iteration number at which the problem has been converged?

I am running a certain code for 100 iterations, using for loop and the fitness is stored in ‘Best Expected Profit’.

The problem converges after a few iterations.

I want to get the number of iteration at which the problem has been converged.

MaxIt=100;   % Maximum Number of Iterations

for it=1:MaxIt

[code for the problem]

end 

Best Expected Profit

For example in this graph, the problem has been converged in 19th iteration.

How do I get this number from the code?

Please help.

Thanks in anticipation!

Just add in an

if bestExpectedProfit == 100
   break
end

and then it will be the iteration you want after the loop. If convergence is based on a tolerance rather than exactly 100 then change condition this accordingly
