getGenConstrMin ( genconstr )

Retrieve the data associated with a general constraint of type MIN. 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 addGenConstrMin for a description of the semantics of this general constraint type.


genconstr: The general constraint object of interest.

Return value:

A tuple (resvar, vars, constant) that contains the data associated with the general constraint:

resvar (Var): Resultant variable of the MIN constraint.

vars (list of Var): Operand variables of the MIN constraint.

constant (float): Additional constant operand of the MIN constraint.

Example usage:

  # x5 = min(x1, x3, x4, 2.0)
  minconstr = model.addGenConstrMin(x5, [x1, x3, x4], 2.0, "minconstr")
  (resvar, vars, constant) = model.getGenConstrMin(minconstr)
