Model.setAttr()
setAttr ( attrname, newvalue )
Set the value of an attribute. Note that, due to our lazy update approach, the change won't actually take effect until you update the model (using Model.update), optimize the model (using Model.optimize), or write the model to disk (using Model.write).
Call this method with two arguments to set a model attribute. Call it with three arguments to set the values of the attribute for a list of variables or constraints.
The full list of available attributes can be found in the Attributes section.
Raises an AttributeError
if the specified attribute doesn't
exist or can't be set.
Arguments:
attrname: Name of attribute to set.
newvalue: Desired new value of attribute.
Example usage:
model.setAttr("objCon", 0) model.setAttr(GRB.Attr.objCon, 0) model.setAttr("LB", m.getVars(), [0]*model.numVars) model.setAttr("RHS", m.getConstrs(), [1.0]*model.numConstrs) model.objcon = 0
