    Does anyone know how to implement a recursive MIP model? If possible, any example that shows the basic idea would be very helpful.

    I am not exactly sure of what you mean by recursive MIP model. If you are looking for an example wherein one model calls itself repeatedly after and changes certain inputs in every iteration, you should go through the 'mulprod' example (under the <CPLEX_StudioXXX>\opl\examples\opl\mulprod folder). If you are looking for a sample with a master and sub problem setup such that the results from each solve are used interactively, then you should go through the 'cutstock' example.

    Here are some doc links which talk about the problem themselves:

    Hope this helps.

    Yes, I was looking for a sample where the model calls itself and changes some of its input data. I will have a look at the samples you suggested.
