In this paper, we … WebbThus, we see two more positive examples and we see our first negative example. If X = B, there are again three neighbors, but only one pair of neighbors, A and C, has an edge. Thus, we have two more negative examples, and one positive example, for a total of seven positive and three negative. Finally, when X = D, there are four neighbors.
