Signal-flow graphs are directed graphs in which nodes represent system variables and branches (edges, arcs, or arrows) represent functional connections between pairs of nodes. Flow graphs are digraphs associated with a set of linear algebraic or differential equations. See more In mathematics, and more specifically in graph theory, a directed graph (or digraph) is a graph that is made up of a set of vertices connected by directed edges, often called arcs. See more Subclasses • Symmetric directed graphs are directed graphs where all edges appear twice, one in each direction … See more For a vertex, the number of head ends adjacent to a vertex is called the indegree of the vertex and the number of tail ends adjacent to a vertex is its outdegree (called See more A directed graph is weakly connected (or just connected ) if the undirected underlying graph obtained by replacing all directed edges of … See more In formal terms, a directed graph is an ordered pair G = (V, A) where • V is a set whose elements are called vertices, … See more An arc (x, y) is considered to be directed from x to y; y is called the head and x is called the tail of the arc; y is said to be a direct successor of x and x is said to be a direct predecessor … See more The degree sequence of a directed graph is the list of its indegree and outdegree pairs; for the above example we have degree sequence ((2, 0), (2, 2), (0, 2), (1, 1)).

WebNov 7, 2014 · That is, every directed edge has the form (v_i, v_j) with i < j. Each node except v_n has at least one edge leaving it. That is, for every node v_i, there is at least one edge of the form (v_i, v_j). Give an efficient algorithm that takes an ordered graph G and returns the length of the longest path that begins at v_1 and ends at v_n. WebWhen each connection in a graph has a direction, we call the graph a directed graph, or digraph, for short. The directed edges of a digraph are thus defined by ordered pairs of vertices (as opposed to unordered pairs of vertices in an undirected graph) and represented with arrows in visual representations of digraphs, as shown below.
