The seven bridges of königsberg

The problem with iron bridges was that the material was not as reliable as carbon steel, so it was replaced starting in the late 1800s and was completely unavailable for bridge building by the early 1900s.

An Eulerian walk (or Eulerian trail) is a walk (resp. trail) that visits every edge of a graph G at least (resp. exactly) once.

The paper he published in 1736, "The Seven Bridges of Königsberg," not only demonstrated that a solution was not possible for the seven bridges problem but also provided a criterion that allows one to quickly determine whether there is a solution for any similar problem with any number of bridges. Two bridges were not restored after WWII and a new bridge replaced two other bridges in 1970's. Plus some other bridges have been built nearby (outside the area delimited by the original seven bridges but within the old "Eulerian" borders of Königsberg). Also, the border of the city has changed since Euler's times.The Seven Bridges of Königsberg is a historically notable problem in mathematics. Its negative resolution by Leonhard Euler in 1736 [1] laid the foundations of graph theory and prefigured the idea of topology. [2]The Seven Bridges of Konigsberg • The problem goes back to year 1736. • This problem lead to the foundation of graph theory. • In Konigsberg, a river ran through the city such that in its center was an island, and after passing the island, the river broke into two parts.

Determining if a Graph is Eulerian. We will now look at criterion for determining if a graph is Eulerian with the following theorem. Theorem 1: A graph G = (V(G), E(G)) is Eulerian if and only if each vertex has an even degree. Consider the graph representing the Königsberg bridge problem. Notice that all vertices have odd degree: Vertex.This negative solution to the Seven Bridges of Königsberg problem represented the beginning of graph theory, topology and network science.
