We see issues in optimizer run where the Optimizer is stuck on subproblem 72/348 and spends the entire remaining time on the one subproblem. Is there any way to provide the optimizer a lower number for maxSubproblemTime so that it can move on to other subproblems and solve them for a good overall solve ?

Appreciate any guidance on this issue.

  Hi Sachin,

  What exactly are your subproblems? Are you referring to multi-objective optimization? In that case please look here for defining custom parameters per multi-objective environment.

  You may also want to specify a MIPGap to terminate the optimization process earlier.

  Cheers,
  Matthias
