In a dynamic bi-level optimization model solved by Gurobi, what can be the reason, for getting infeasible results for first two or three iterations and then feasible results for next iterations?

  Hi Mary,

  There can be many reasons for infeasibility. The probably best way would be to write out the models constructed in the first iterations via the write() method and analyze them. The Knowledge Base article How do I determine why my model is infeasible? holds all essential information for this analysis.

  Best regards,
  Jaromił
