“…Clearly definition (9) gives at least the same value as definition (8). To see that these definitions are equivalent we need to show that for every G ′ , G ′′ ∈ F (G) there exits H ∈ CF (G) such that G ′′ ⊆ H and ξ(G ′ ) ≤ ξ(H).…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
