Abstract

In this chapter, we address the question: given a graph, does it have a trilateration order? And if so, is it contiguous? Unlike the DGP, which is not known to be in NP, these order existence problems are both in NP: if a graph is a YES instance, a suitable vertex order can be verified to be correct in polytime, by simply checking that it has enough adjacent predecessors.
