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 .
First edition. Graph Theory, 1736–1936 is a book in the history of mathematics on graph theory.It focuses on the foundational documents of the field, beginning with the 1736 paper of Leonhard Euler on the Seven Bridges of Königsberg and ending with the first textbook on the subject, published in 1936 by Dénes Kőnig.
The Königsberg bridge problem is a mathematical challenge from the 18th century. [8] It asks to find a route that leads the walker across each of the seven historical bridges in the city of Königsberg such that each bridge is crossed exactly once.

The numbers denote the number of edges connected to each node. Nodes with an odd number of edges are shaded orange. Width: 100%: Height: 100%
In 1736, the Swiss mathematician Leonhard Euler used the arrangement of the city's bridges and islands as the basis for the Seven Bridges of Königsberg Problem, which led to the mathematical branches of topology and graph theory.
Seven Bridges of Königsberg – Walk through a city while crossing each of seven bridges exactly once. [ 6 ] Squaring the circle , the impossible problem of constructing a square with the same area as a given circle, using only a compass and straightedge .
In 1736 Euler solved, or rather proved unsolvable, a problem known as the seven bridges of Königsberg. [8] The city of Königsberg, Kingdom of Prussia (now Kaliningrad, Russia) is set on the Pregel River, and included two large islands which were connected to each other and the mainland by seven bridges. The question is whether it is possible ...
