A marked graph is a Petri net in which every place has exactly one incoming arc, and exactly one outgoing arc.: 561  This means, that there can not be...

An augmented marked graph is basically a Petri net with a specific set of places called resource places. If removing these resource places and their associated...

In graph theory, a bridge, isthmus, cut-edge, or cut arc is an edge of a graph whose deletion increases the graph's number of connected components. Equivalently...

computer science, graph traversal (also known as graph search) refers to the process of visiting (checking and/or updating) each vertex in a graph. Such traversals...

mathematical field of graph theory, a quartic graph is a graph where all vertices have degree 4. In other words, a quartic graph is a 4-regular graph. Several well-known...

mathematical field of graph theory, the Erdős–Rényi model refers to one of two closely related models for generating random graphs or the evolution of a...

The following figure shows examples of edge coverings in two graphs (the set C is marked with red). A minimum edge covering is an edge covering of smallest...

mathematics, a queen's graph is an undirected graph that represents all legal moves of the queen—a chess piece—on a chessboard. In the graph, each vertex represents...

In graph theory, a vertex cover (sometimes node cover) of a graph is a set of vertices that includes at least one endpoint of every edge of the graph. In...
