Abstract: A network reachability solving algorithm based on formal verification, which abstractly models the network reachability problem, concretely models and refines it through semantic equivalence, and implements the network reachability solving algorithm through logical equivalence transformation. With the help of formal verification tools, the present disclosure ensures the correctness and logical completeness of the reachability solving algorithm through mathematical reasoning. Compared with traditional testing-based schemes, the present disclosure guarantees the correctness and effectiveness of the network reachability algorithm based on formal method.

Abstract: Systems, methods, and non-transitory computer readable media can determine a plurality of potential recipients of a content item associated with a user. The plurality of potential recipients can be ranked based on a likelihood of the user engaging with the plurality of potential recipients. At least some of the plurality of potential recipients can be provided in a sheet for selecting one or more recipients of the content item, based on the ranking.
