• Eulerian digraphs and oriented trees. A famous problem which goes back to Euler asks for what graphs G is there a closed walk which uses every edge exactly once. (There is also a version for non-closed walks.) Such a walk is called an Eulerian tour (also known as an Eulerian cycle). A graph which has an Eulerian tour is called an Eulerian graph. Paths and Circuits. Graph theory began in the year 1736 when Leonard Euler published a paper that contained the solution to the 7 bridges of Königsberg problem. If vertices v and w are part of a circuit in G and one edge is remove from the circuit, then there still exists a path from v to w in G.

• A connected graph G is an Euler graph if and only if it can be decomposed into cycles. Proof. Suppose graph G can be decomposed into cycles; that is, G is a union of edge-disjoint cycles. Since the degree of every vertex in a circuit is two, the degree of every vertex in G is even. Hence G is an Euler graph. Conversely, let G be an Euler graph. Euler circuits exist when the degree of all vertices are even. A graph with more than two odd vertices will never have an Euler Path or Circuit. A graph with one odd vertex will have an Euler Path but not an Euler Circuit.

Thus, Euler’s assertion that a graph possessing such a path has at most two vertices of odd degree was the first theorem in graph theory. Euler described his work as geometria situs—the “geometry of position.” so im learning Euler circuit now, and i found this algorithm 'tour' is a stack find_tour(u): for each edge e=(u,v) in E: remove e from E find_tour(v) prepend u to tour to find the tour, clear stack 'tour' and call find_tour(u), where u is any vertex with a non-zero degree. Motivation: Consider a network of roads, for example. If it is possible to walk on each road in the network exactly once (without magically transporting between junctions) then we say that the network of roads has an Eulerian Path (if the starting and ending locations on an Eulerian Path are the same, we say the network has an Eulerian Circuit). Longest non-touching path on a square grid I have a square grid (in particular, I am interested in the 16x16 case), in which i can draw a path (a sequence of laterally adjacent grid cells).

They will also be able to provide an algorithm for an Euler path or circuit for a given graph. They will be able to look at a graph and know if it will be possible to find an Euler path or circuit. Vocabulary: 1. Fleury's Algorithm for finding an Euler circuit or path: - Start at a vertex of odd degree, or, if the graph has none, start with an arbitrarily chosen vertex. - At each step, pick the next edge in the path to be one whose deletion would not disconnect the graph, i.e., pick an edge that is not a bridge if possible. The only way to make this installation safe from a ground fault is to bond service equipment to an effective ground-fault current path so that the fault current will be more than sufficient to quickly open the circuit protection device; thereby clearing the ground fault and removing dangerous touch voltage [250.2, 250.4(A)(3), and 250.24(C)].
