A fuzzy graph G is a pair of functions (σ, μ) where σ is a fuzzy subset of a non empty set V and μ is a symmetric fuzzy relation on σ. The underlying crisp graph of G:(σ, μ) is denoted by G*(V, E) where

Returns the strong product of G and H. The strong product P of the graphs G and H has a node set that is the Cartesian product of the node sets, V ( P) = V ( G) × V ( H) . P has an edge ( ( u, v), ( x, y)) if and only if u == v and ( x, y) is an edge in H, or x == y and ( u, v) is an edge in G, or ( u, v) is an ...
WebThe curve is somewhat asymmetrical because the steady increase in the volume of the solution during the titration causes the solution to become more dilute. Due to the leveling effect, the shape of the curve for a titration involving a strong acid and a strong base depends on only the concentrations of the acid and base, not their identities.
