GAMS.GAMSModifier Class Reference

Instances of this class are input to GAMSModelInstance.Instatiate. A GAMSModifier consists either of a GAMSParameter or a triple: A GAMSVariable or GAMSEquation to be modified, the modification action (e.g. . Upper, Lower or Fixed for updating bounds of a variable, or Primal/Dual for updating the level/marginal of a variable or equation mainly used for starting non-linear models from different starting points), and a GAMSParameter that holds the data for modification. In addition the UpdateType can be defined (if ommitted the type defined in the Solve call is used). More...
