Eulerian and Hamiltonian Paths 1. Euler paths and circuits 1.1. The Könisberg Bridge Problem Könisberg was a town in Prussia, divided in four land regions by the river Pregel. The regions were connected with seven bridges as shown in figure 1(a). The problem is to find a tour through the town that crosses each bridge exactly once.

An Euler path (or Eulerian path) in a graph \(G\) is a simple path that contains every edge of \(G\). The same as an Euler circuit, but we don't have to end up back at the beginning. The other graph above does have an Euler path. Theorem: A graph with an Eulerian circuit must be connected, and each vertex has even degree.

Hence an Euler path exists in the pull-down network. In the pull-up network, there are also exactly 2 nodes that are connected to an odd number of transistors: V_DD and J.
