Königsberg Bridge Problem

The Königsberg Bridge Problem involves finding a route that crosses each of the seven bridges in the city of Königsberg exactly once without retracing any path. It asks whether such a walk is possible. Mathematician Leonhard Euler analyzed this problem in the 18th century and demonstrated that it’s impossible because of the way the bridges connect the landmasses, which creates certain limitations on the paths. This problem is foundational in graph theory, illustrating how complex problems can be modeled with nodes and connections, and it paved the way for solving similar routing and network issues today.
