Webtions. Computation in Datalog consists of monotonic logical inferences that apply to produce more facts until fixpoint. A Datalog rule “C(z,x) ←A(x,y), B(y,z).” means that if A( ) and B(y,z) are both true, then C(z,x) can be inferred. The DOOP framework [4] is a prominent instance of the Datalog approach to static analysis. DOOP is an ...

With the choice construct we can express worklist algorithms such as spanning trees in a few lines of code. WebLecture 9: Datalog with Negation 9-3 Notice that (P2) defines the IDB R, and (P3) defines TC; TC has a negated IDB in the body of a rule that defines it, but this IDB appears in the previous stratum (P2). A Datalog:program can have many possible stratifications.For instance, in the above example we could switch the order of (P1), (P2) and still get a …
