“…A fuzzy graph G = (V, µ, σ) [3] is a nonempty set V together with a pair of functions µ : V −→ [0, 1] and σ : V × V −→ [0, 1] such that for all u, v ∈ V , σ(u, v) = σ(uv) ≤ µ(u) ∧ µ(v). We call µ the fuzzy vertex set of G and σ the fuzzy edge set of G. Here after we denote the fuzzy graph G(µ, σ) simply by G and the underlying crisp graph of G by G * (V, E) with V as vertex set and E = {(u, v) ∈ V × V : σ(u, v) > 0} as the edge set or simply by G * .…”
