Abstract

The computational results section of the article present the following erroneous information: • Table 4, Page 94: the values of λ in the first column should have been in decreasing order (i.e., the first row [formula presented] in the last row [formula presented]) and not in increasing order as reported.• Tables A2–A4 in the Appendix: The values in the column Total time(s) have not been computed correctly for the instances starting with Golden11 for [formula presented] due to a typing error. These values should be recomputed by summing the values of the columns Avg. time (s) and Preproc. (s). With this modification, the average CPU time across the Golden instances for the algorithm UHGSp becomes 856.16 s (instead of 854.94 s), and Tables 2–4 (Pages 93–94) should be updated as follows (updated numbers are displayed using boldface characters).
