What do Shannon-type Inequalities, Submodular Width, and Disjunctive Datalog have to do with one another?
Summary: Relates Shannon-type (Shannon flow) information inequalities to output-size bounds for disjunctive Datalog (generalizing CQs) under FDs, degree and input-cardinality bounds via “proof sequences”. Uses these sequences to drive PANDA, yielding algorithms that match fractional hypertree and exactly submodular-width runtimes. (summarized by gpt-5-mini on Feb 09 2026)
