2 Interpretations and Models (with variables)
1 Models and Logical Consequences (ground)
Given the knowledge base:
a <- b & c. a <- g. b <- d. b <- f. c <- e. d <- h. e. f <- e.
where
{a,b,c,d,e,f,g,h}
is the set of all atoms.
Give a model of the knowledge base.
Give an interpretation that is not a model of the knowledge base.
Give two atoms that are logical consequences of the knowledge base.
Give two atoms that are not logical consequences of the knowledge base.
