An undirected graph is a graph in which the nodes are connected by undirected arcs . An undirected arc is an edge that has no arrow. Both ends of an undirected arc are equivalent--there is no head or tail.

Graph theory: undirected graphs; Author: includeh10; Section: C / C++ Language; Chapter: Languages ... Graphic theory is called vertex-edge theory also, which includes undirected and directed graphs. Programming for directed and undirected graphs is almost the same, if you understand one, you know another one at once.

The Minimum Spanning Tree of an Undirected Graph ... An unrooted tree is a connected, acyclic, undirected graph. Each leaf vertex has degree one, i.e. is connected to one other vertex. ... This is better than Prim's algorithm for sparse graphs for which |E|<<|V|2.

Much of the terminology for directed graphs is also applicable to undirected graphs. For example, vertices v and w are adjacent if (v, w) is an edge [or, equivalently, if (w, v) is an edge]. We say the edge (v, w) is incident upon vertices v and w.

Two very frequently asked questions in the context of LEDA's graph types are how LEDA distinguishes between directed and undirected graphs and how to create a directed or an undirected graph.
