WebDec 30, 2014 · 2 Answers. This is not a interval graph since we have the edges a b a d c b and c d but we do not have a c or b d. Why this leads to a contradiction: Assume that it is an interval graph. This means that the intervals b and d have empty intersection so the intervals are disjoint. But the interval a intersects both b and d. WebThe second input is the sequential set of vertices of the graph. The third input is the value of m.
