The upper bound comes to a wrong value while using the callback feature of the algorithm. The same formula works for non-callback version. What is the criteria for checking the convergence of the bounds in callback version.

  Hi Soumya,

  Can you please be a bit more specific?
  What do you mean with callback- and non-callback version?
  What exactly are you doing in the callback?
  What do you mean with wrong upper bound value?

  Best regards,
  Mario
