GRBModel.ChgCoeffs()


GRBModel.ChgCoeffs()

Change a list of coefficients in the model. Each desired change is captured using a GRBVar object, a GRBConstr object, and a desired coefficient for the specified variable in the specified constraint. The entries in the input arrays each correspond to a single desired coefficient change. The lengths of the input arrays must all be the same. If you make multiple changes to the same coefficient, the last one will be applied.

Note that the changes won't take effect until the next call to GRBModel.Optimize or GRBModel.Update on that model.

void ChgCoeffs ( GRBConstr[] constrs,
    GRBVar[] vars,
    double[] vals )
    Arguments:

    constrs: Constraints for coefficients to be changed.

    vars: Variables for coefficients to be changed.

    vals: Desired new values for coefficients.
