exif: {"Image DocumentName": "Euler\u2019s GraphDefine the degree of a vertex to be the number of edges incident to it.", "Image ImageDescription": "Euler showed that there is a walk starting at any vertex, going through each edge exactly once and terminating at the start vertex iff the degree of each vertex is even. This walk is called Eulerian. No Eulerian walk of the Konigsberg bridge problem since all four vertices are of odd edges.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
