Here is the problem:

“k” is a parameter in optimization problem A, for a specific “k1”, we can get the optimum solution “S1” for problem “A”. Now I hope the solution “S” is closer to a specific solution “S*”, so I will need to change the “k” to minimize |S-S*|. How can I formulate this double-layer problem in AIMMS?

Hi @Chunyang. Without knowing anything about parameter k the best you can do I think is to loop over k, using some fixed interval, and solve the model for each k.

Yeah, it does a solution, but it means I can’t get the precise value for the best k. Thanks a lot anyway!

Whether k can be used as a variable depends on how k is used in your model. I can only advise on that if you share your model.

Thanks a lot, I don’t have the model now, it’s just an initial thought. I will try to complete the thought first.
