Add a new general constraint of type GRB.GENCONSTR_NORM to a model.

A NORM constraint <span>$</span>r = \mbox{norm}\{x_1,\ldots,x_n\}<span>$</span> states that the resultant variable <span>$</span>r<span>$</span> should be equal to the vector norm of the argument vector <span>$</span>x_1,\ldots,x_n<span>$</span>.

GRBGenConstr AddGenConstrNorm ( GRBVar resvar,
    GRBVar[] vars,
    double which,
    string name )


resvar: The resultant variable of the new constraint.

vars: Array of variables that are the operands of the new constraint. Note that this array may not contain duplicates.

which: Which norm to use. Options are 0, 1, 2, and GRB.INFINITY.

name: Name for the new general constraint.

Return value:

New general constraint.
