The function that returns a decision (Element[U]) given the value of the parent T.
The function that returns a decision (Element[U]) given the value of the parent T.
The function that returns the expected utility (Element[Double]) given the value of the parent T.
The function that returns the expected utility (Element[Double]) given the value of the parent T.
An exact decision policy. This policy is exact because every possible value of the parent must have a defined policy. This makes it suitable for variable elimination algorithms or sampling algorithms if the range of the parent is small and enough samples are generated.
