WebAs in Datalog, the goal of Formulog evaluation is to compute all possible inferences with respect to the rules, which correspond to logical implications. Unlike Datalog, rule evaluation might involve both ML evaluation and calls to an SMT solver. The way this design combines Datalog, ML, and SMT solving gives Formulog some desirable properties.
