However, the configuration of the 45 major bridges in Bristol is such that an Eulerian circuit exists. [15] This cycle has been popularized by a book [15] and news coverage [16] [17] and has featured in different charity events.

Mutilated chessboard problem – Place 31 dominoes of size 2×1 on a chessboard with two opposite corners removed. [4] Coloring the edges of the Petersen graph with three colors. [5] Seven Bridges of Königsberg – Walk through a city while crossing each of seven bridges exactly once. [6]
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 correspondence itself is lost, but we can find the main thread of their relationship with Euler's first letter of response. In the letter, Euler talks of the problem of the Seven Bridges of Königsberg, a problem that Ehler brought to Euler's attention. The reason for such an inquiry was the desire by Kuhn and Ehler to encourage ...
Bottom: A solution on a torus — the dotted line is on the back side of the torus Comparison of the graphs of the Seven bridges of Konigsberg (top) and Five-room puzzles (bottom). The numbers denote the number of edges connected to each vertex.
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 ...
The Seven Bridges of Königsberg is a historically notable problem in mathematics. Its negative resolution by Leonhard Euler in 1736 laid the foundations of graph theory and prefigured the idea of topology.
