Variable relative solution tolerance in GamsModelInstance
Posted: Wed Oct 24, 2018 7:19 pm
I need to solve a model with multiple varying data (thus the use of GamsModelInstance) several times with varying accuracy (start at lower accuracy and progress towards OptCr=0).
As far as I am aware, the OptCr option is set for the GamsCheckpoint from which the GamsModelInstance is created.
Recreating a new GamsModelInstance (with all the Modifiers, instantiation etc.) each time the solution tolerance needs to be tightened seems a bit unwieldy.
Is it possible to directly change these parameters for the existing GamsModelInstance, without re-instantiation?
