WebBasic Graph Theory. Graph. A graph is a mathematical structure consisting of a set of points called VERTICES and a set (possibly empty) of lines linking some pair of vertices. It is possible for the edges to oriented; i.e. to be directed edges. The lines are called EDGES if they are undirected, and or ARCS if they are directed. WebDefinitions Tree. A tree is an undirected graph G that satisfies any of the following equivalent conditions: . G is connected and acyclic (contains no cycles).; G is acyclic, and a simple cycle is formed if any edge is added to G.; G is connected, but would become disconnected if any single edge is removed from G.; G is connected and the 3-vertex …
