Test Problems for Partial Digest

TEST_PARTIAL_DIGEST, a C++ code which can generate example cases of the partial digest problem.

In the partial digest problem, we assume that there are N objects arranged along a line. We denote the position of object I by X(I). The positions of the objects are unknown. Instead, we have a list of the distances between every distinct pair of objects. Note that the distances are not "tagged"; that is, if there is a 175 on the list of distances, we don't know which two objects are separated by that distance. In the partial digest problem, we start with the (N*(N-1))/2 distances D, and must come up with at least one linear arrangement of N objects that corresponds to the distances.

To use this library, the user specifies a number of objects N, and a maximum separation DMAX. The library will generate N object locations in an array called LOCATE, and the corresponding list of distances D.
