Euler walk.

Euler devised a mathematical proof by expressing the situation as a graph network. This proof essentially boiled down to the following statement (when talking about an undirected graph): An Eulerian path is only solvable if the graph is Eulerian, meaning that it has either zero or two nodes with an odd number of edges.

An Euler circuit starts and ends at the same vertex." According to my little knowledge "An eluler graph should be degree of all vertices is even, and should be connected graph". is a closed walk containing all of those edges. The degreeof the face is the minimum length of a boundary walk. For example, in the figure below, the lefthand graphhas three faces. The boundary offace 2has edges df,fe,ec,cd, so this face has degree 4. The boundary of face 3 (the unbounded face) has edges bd,df,fe,ec,ca,ab, so face 3 has degree 6.Here, 1->2->3->4->2->1->3 is a walk. Walk can be open or closed.
