Graph directed
WebAn oriented graph is an undirected graph with orientation. Think of it this way, every oriented graph is a directed graph, but not viceversa. Every oriented graph can be obtained by taking a simple undirected graph and assigning a direction to every edge. This is not true for every directed graph. Basically directed graphs can have an arrow ... WebDescribing graphs. A line between the names of two people means that they know each other.

Directed acyclic graphs can also be used as inputs to neural networks, and I've seen at least one paper where undirected molecular graphs have been converted to directed acyclic graphs to use as inputs for a machine learning …
WebDirected Graph: A graph in which an edge (u,v) doesn't necessarily mean that there is an edge (v, u) as well. The edges in such a graph are represented by arrows to show the direction of the edge. Graph … Subclasses Symmetric directed graphs are directed graphs where all edges appear twice, one in each direction (that is, for every arrow that belongs to the digraph, the corresponding inverse arrow also belongs to it). (Such an edge is sometimes called "bidirected" and such graphs are sometimes called … 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 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 … 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 … See more • Binary relation • Coates graph • DRAKON flowchart • Flow chart 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, nodes, or points; • A is a set of ordered pairs of vertices, called arcs, directed edges (sometimes simply edges with the … 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 … See more A directed graph is weakly connected (or just connected ) if the undirected underlying graph obtained by replacing all directed edges of the graph with undirected edges is a connected graph.
