[@berman2000] taken from the protein data bank (PDB) [@PDB2015], see Table \[tab:proteins\]. These proteins range from small globular proteins with 50 amino acids to large proteins with about 700 amino acids. We only consider *ATOM* entries in the file, which provide atomic coordinates. Also, we only work on the first chain in the case of multiple protein chains. Based on the coordinates of a protein, we can construct an instance for the various distance geometry problems. For each experiment we actually create three instances per protein ([*i.e.,* ]{}different contact distance information) to eliminate effects of particularly good/bad sets of input data. Also, each instance ([*i.e.,* ]{}same contact distance information) is re-run three times to eliminate stochasticity effects. The displayed data per protein are averaged over these three instances and three respective runs.
