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

An ABS constraint <span>$</span>r = \mbox{abs}\{x\}<span>$</span> states that the resultant variable <span>$</span>r<span>$</span> should be equal to the absolute value of the argument variable <span>$</span>x<span>$</span>.

GRBGenConstr addGenConstrAbs ( GRBVar resvar,
GRBVar argvar,
String name )


resvar: The resultant variable of the new constraint.

argvar: The argument variable of the new constraint.

name: Name for the new general constraint.

Return value:

New general constraint.
