Restart with Solver Foundation Services

Question

Hello,

Is it possible to change bounds on decision variables (the domain ie the min, max on the variable) and the constraint restriction value (the RHS and LHS) after a solve is done and then call Solve again such that the solver behind uses restart to solve the changed model (so not doing a complete new solve from scratch)?

I can acces the constraints from the model, but the Expression property on it is a string and I would expect a Term so that I can modified it.

Also with the Decisions on the model, I don't see a way how to acces the domain on them or how to modify the domain.

Does this mean that this feature is not available in Foundation Services?

Best regards

Hello there - The Term object is read-only, as is the constraint objects. Therefore the feature you are looking for is not (currently) available in SFS. If you want this functionality then I would consider programming against the ILinearModel interface (the solver level API) directly.
