I am trying to implement a custom heuristic and cut callback. I need to test multiple instances, and the cuts would be dependent on some characteristics of each instance, retrieved from a data file.

My question is: is there a way to read problem data (like a .dat file in ampl) using the Gurobi C++ API? And if so, is there any specif format that must be used? I could not find any information on the website.

I know there is the option of reading .mps files, and I also know that the python API can be set up to read excel files (e.g, the diet4.py example). However, I am using the c++ api and to adequately customize my model, I need to read the coefficients from a data file and then use it to build the model.

Any help would be greatly appreciated.
