Relations To Other Models
The well-founded semantics can be viewed as a three-valued version of the stable model semantics. Instead of only assigning propositions true or false, it also allows for a value representing ignorance.
For example, if we know that
Specimen A is a moth if specimen A does not fly during daylight.
but we do not know whether or not specimen A flies during the day, the well-founded semantics would assign the proposition ``specimen A is a moth`` the value bottom which is neither true nor false.

Famous quotes containing the words relations and/or models:
“Think of the many different relations of form and content. E.g., the many pairs of trousers and what’s in them.”
—Mason Cooley (b. 1927)
“The parents who wish to lead a quiet life I would say: Tell your children that they are very naughty—much naughtier than most children; point to the young people of some acquaintances as models of perfection, and impress your own children with a deep sense of their own inferiority. You carry so many more guns than they do that they cannot fight you. This is called moral influence and it will enable you to bounce them as much as you please.”
—Samuel Butler (1835–1902)
