Partial Digest is hard to solve for erroneous input data

The Partial Digest problem asks for the coordinates of m points on a line such that the pairwise distances of the points form a given multiset of (m 2 ) distances. Partial Digest is a well-studied problem with important applications in physical mapping of DNA molecules. Its computational complexity status is open. Input data for Partial Digest from real-life experiments are always prone to erro...
