Seven bridges of königsberg

Computer Science. Computer Science questions and answers. 19 pts] The lesson 12 introduced a story about the town of Königsberg in which seven bridges connect lands, as shown in the Figure 1. Historically a famous question has arose in the city, that is, is it possible to walk through town crossing each bridge exactly once, and return to start?

Step 3: Determine if the graph has an Eulerian circuit. In this case, regions A and B have odd degrees, while regions C and D have even degrees. Since not all vertices have even degrees, the graph does not have an Eulerian circuit. Therefore, it is not possible for someone to cross all nine bridges exactly once and return to the starting point.The town of Königsberg was cut into four separate land masses by the river Pregel (Green). At the time, Königsberg was a large trading city, valuable because of its position on the river. The prosperity of the city allowed the people to build seven bridges so citizens could traverse through these four separate land masses with ease.The Seven Bridges of Königsberg is a famous mathematical problem based on the city of Königsberg, now Kaliningrad, set on both sides of the Pregel River along with two islands.
