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)
