Seven bridges of königsberg
The roots of graph theory lead back to the puzzle of Königsberg's bridges. In 1736 Leonhardt Euler published a paper on this problem, and also proposed a solution for it.The Seven Bridges of Königsberg is a historically famous problem in mathematics. Leonhard Euler solved the problem in 1735. This led to the beginning of graph theory. This then led to the development of topology . The city of Königsberg in Prussia (now Kaliningrad, Russia) was set on both sides of the Pregel River. I was commissioned to remake the map of the city of Königsberg produced by German cartographer Johann Homann (1664 - 1724) for his Grand Atlas of all the World, focusing on the part of the map that includes the city's famous seven bridges. 118124 The only major elements to be added that are completely absent are the interior waterway shading, the map labels, and variations of tree sizes and ...

Konigsberg is a town on the Preger River, which in the 18th century was a German town, but now is Russian. Within the town are two river islands that are connected to the banks with seven bridges (as shown below). It became a tradition to try to walk around the town in ...

But only some types of graphs have these Euler Paths, it de...Königsberg was built on both of the Pregel's banks, as well as a river island, past which the river split in two. The city constructed several bridges to connect its different parts, and these inspired the problem of the seven bridges of Königsberg. The problem asked whether people could walk around the city by crossing each bridge only once.The seven bridges of Königsberg. Wikipedia article. Euler's Solution: The Degree of a Vertex.
The Seven Bridges of Königsberg is a famous problem in mathematics that was first posed by Carl Gottlieb Ehler (1685–1753), a mathematician and mayor of the nearby town in 1736.
