Model.getGenConstrNorm()
getGenConstrNorm ( genconstr )
Retrieve the data associated with a general constraint of type NORM. Calling this method for a general constraint of a different type leads to an exception. You can query the GenConstrType attribute to determine the type of the general constraint.
See also addGenConstrNorm for a description of the semantics of this general constraint type.
Arguments:
genconstr: The general constraint object of interest.
Return value:
A tuple (resvar, vars, which) that contains the data associated with the general constraint:
resvar (Var): Resultant variable of NORM constraint.
vars (list of Var): Operand variables of NORM constraint.
which (float): Which norm (possible values are 0, 1, 2, or GRB.INFINITY).
Example usage:
# x5 = norm2(x1, x3, x4) normconstr = model.addGenConstrNorm(x5, [x1, x3, x4], 2.0, "normconstr") model.update() (resvar, vars, which) = model.getGenConstrNorm(normconstr)
