According to Sherafat (2004), the inhabitants of this city had wondered if it would be possible to cross the seven
bridges in the Pregel River, crossing each bridge only once, and returning to point of origin. In the eighteenth

of the Königsberg Bridges", demonstrating through a representation called graph the impossibility of a journey with
these characteristics.
