Graph theory bridge
WebNow Back to the Königsberg Bridge Question: Vertices A, B and D have degree 3 and vertex C has degree 5, so this graph has four vertices of odd degree. So it does not … WebSolution of Konigsberg Bridge problem. In 1735, this problem was solved by Swiss mathematician Leon hard Euler. According to the solution to this problem, these types of walks are not possible. With the help of following graph, Euler shows the given solution. The vertices of this graph are used to show the landmasses.
