Bridges of konigsberg
Once upon a time, a small boy was born in the town of Basel, Switzerland. His parents, impressed by the intelligent look in his eyes, named him Leonhard Euler, after his great uncle Leonhard, who had been smart enough to marry a countess and now lived in the castle, giving him the right to treat his relatives like dirt. Download chapter PDF.The reader is introduced to the Bridges of Königsberg problem made famous by the eighteenth-century Swiss mathematician, Leonhard Euler. The reader is led to understand that the problem has no solution.

The city of Konigsberg, Northern Germany has a significant role in Euler's life and in the history of graph theory. The River Pregel flowed through Konigsberg, separating it into four land areas. Seven bridges were built over the river that allowed the citizens of Konigsberg to travel between these land areas. Back in the 17th century the

Seven Bridges of Königsberg. The Seven Bridges of Königsberg is a historically famous problem in mathematics. Leonhard Euler solved the problem in 1735. This led to the beginning of graph theory. This then led to the development of topology . The city of Königsberg in Prussia (now Kaliningrad, Russia) was set on both sides of the Pregel River. The basic properties of a graph include: Vertices (nodes): The points where edges meet in a graph are known as vertices or nodes. A vertex can represent a physical object, concept, or abstract entity. Edges: The connections between vertices are known as edges. They can be undirected (bidirectional) or directed (unidirectional).To solve the metagenome assembly, the team of UC San Diego’s Pavel Pevzner used the algorithmic approach that is not unlike solving the “Seven Bridges of Konigsberg” puzzle, which asks ...
