GRBModel.chgCoeff()

Change one coefficient in the model. The desired change is captured using a GRBVar object, a GRBConstr object, and a desired coefficient for the specified variable in the specified constraint. If you make multiple changes to the same coefficient, the last one will be applied.

Note that the change won't take effect until the next call to GRBModel.optimize or GRBModel.update on that model.

Arguments:

constr: Constraint for coefficient to be changed.

var: Variable for coefficient to be changed.

newvalue: Desired new value for coefficient.
