Detailed Description

Instances of this class are input to GamsModelInstance.instantiate()

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).

◆ init()

def gams.control.execution.GamsModifier.__init__	(	self,
		gams_symbol,
		update_action = `None`,
		data_symbol = `None`,
		update_type = `SymbolUpdateType._Inherit`
	)

Constructor.

Parameters

gams_symbol	Symbol in the GAMS model to be modified. This can be a GamsParameter, GamsVariable or GamsEquation. If a variable or an equation is specified a data_symbol and an update_action have to be specified as well.
update_action	Modification action
data_symbol	Parameter containing the data for the modification
update_type	Symbol Update Type (default: Inherit from model instance)
