For example, we drew Q_3 in a non-planar way originally, but it is actually planar: Like being bipartite or isomorphic, we can't just draw the graph one way and decide it's not planar. Bipartite Graphs Embedding is the process of rearranging a graph's known form onto a host graph.. For this project the only host graph we are interested in is a grid. If every vertex of a nonempty graph has even degree and is connected, then the graph has an Euler circuit. This graph is defined as the complete bipartite graph, i.e., it is a graph with 4 vertices and 3 edges, all sharing a common vertex, with the other vertex free to vary. The maximum degree of a graph is. K2,3 K3,3 K3,5 K2,6 FIGURE 9 Some Complete Bipartite Graphs. 1.
