WebTheorem 2: A given connected graph G is an Euler graph if and only if all vertices of G are of even degree Proof: Suppose that G is and Euler graph. Which contains a closed walk called Euler line. In tracing this walk, observe that every time the walk meets a vertex v it goes through two “new” edges incident on v – with one we entered v ... WebA graph is a symbolic representation of a network and its connectivity. It implies an abstraction of reality so that it can be simplified as a set of linked nodes. The origins of graph theory can be traced to Leonhard Euler, who devised in 1735 a problem that came to be known as the “Seven Bridges of Konigsberg”. hierarchy of royalty titles
