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. [18] Comparison of the graphs of the Seven bridges of Konigsberg (top) and Five room puzzle (bottom). The numbers ...
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.
Multigraphs of both Königsberg Bridges and Five room puzzles have more than two odd vertices (in orange), thus are not Eulerian and hence the puzzles have no solutions. Every vertex of this graph has an even degree. Therefore, this is an Eulerian graph. Following the edges in alphabetical order gives an Eulerian circuit/cycle.

The bridge problem inspired the Bristol Bridges Walk. 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.
