A circuit is a non-empty trail in which the first and last vertices are equal (closed trail).; Let G = (V, E, ϕ) be a graph. A circuit is a non-empty trail (e 1, e 2, …, e n) with a vertex sequence (v 1, v 2, …, v n, v 1).. A cycle or simple circuit is a circuit in which only the first and last vertices are equal.; Directed circuit and directed cycle
