Nor was the problem forgotten in Königsberg; in 1875. L.

The Bridges of Konigsberg. Age 11 to 18. Challenge Level. Konigsberg (now called Kaliningrad) is a town which lies on both sides of the Pregel River, and there are also parts of the town on two large islands that lie in the river. In the 18th century the river banks and islands were connected with seven bridges (as shown below). Königsberg, 1736 Leonard Euler (a Swiss mathematician) made many contributions to the fields of mathematics, topology, mechanics, fluid dynamics, astronomy and even music theory. He introduced ...

The Konigsberg bridges have the interesting property that adding or deleting a bridge between any two landmasses will allow an Eulerian path. Indeed, adding or deleting a bridge will change the parity of the degrees of two of the four vertices of the associated graph, which will make them both even.

Like Konigsberg Bristol spans the two banks of a river and two river islands. The Bristol Bridges walk is an Eulerian cycle crossing all 45 major bridges in the city. It has been the subject of the several articles in newspapers and magazines, and there is a book about the walk. An important historical event regarding the significance of problem representation can be found in the story of Leonhard Euler (1707-1783) and the seven bridges of Königsberg problem ...In short, seven bridges connect the four main geographi-cal areas of Konigsberg, but only one or two of these areas can serve as start¨ and finish of the sought-after path through the city. This means that at least two areas must be traversed and, in order to do so, must be connected by an even number of bridges across the river Pregel.

In 1735 he was able to prove that it was not possible to walk through the city of Königsberg (now Kaliningrad) crossing each of its seven bridges only once—because of the layout of islands in the Pregel River (fig. 1). Leonard Euler, a Swiss mathematician, made many contributions to the fields of mathematics, topology, mechanics, fluid dynamics, astronomy and even music theory. He introduced much of the…Euler reached several conclusions. First, he found that if more than two of the land areas had an odd number of bridges leading to them, the journey was impossible. Secondly, Euler showed that if exactly two land areas had an odd number of bridges leading to them, the journey would be possible if it started in either of these two areas. It contained two islands and there were seven bridges linking the various land masses. A famous puzzle at the time was to find a walk through the city that crossed every bridge …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.
