Web2 1. Graph Theory At first, the usefulness of Euler’s ideas and of “graph theory” itself was found only in solving puzzles and in analyzing games and other recreations. In the mid 1800s, however, people began to realize that graphs could be used to model many things that were of interest in society. For instance, the “Four Color Map ... WebHistory of Graph Theory Graph theory emerged from the Konigsberg bridge problem in 1736 by Swiss mathematician, L Euler. Konigsberg is a small town located in the European continent. In the city, there is a big river and there are two deltas (small island). FIGURE 1. (a) Konigsberg Bridges, (b) Graph that represents Konigsberg Bridges.

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. The city of Königsberg in Prussia (now Kaliningrad, Russia) was set on both sides of the Pregel River, and included two large islands—Kneiphof and Lomse—which were connected to each other, an… WebThe first step was to transform the actual diagram of the city and its bridges into a graph. The use of the word graph in this context may be different than what most people think of when they see the word graph. In this case, a graph must have vertices and edges. Furthermore, a graph must have a rule that tells how the edges join the various ...
