The OPTNET procedure can be used to analyze relationships between entities. These relationships are typically defined by using
a graph. A graph, 
, is defined over a set 
of nodes and a set 
of arcs. A node is an abstract representation of some entity (or object), and an arc defines some relationship (or connection) between two nodes. The terms node and vertex are often interchanged when describing an entity. The term arc is often interchanged with the term edge or link when describing a connection.
