A few of the results for the 15- and 30-department problems (Tables 2 and 3) reported by us in our paper1 were incorrect (because of certain typographical errors in the input data). The correct results have now been obtained and differ from the incorrectly reported ones only slightly; some of the new results actually represent an improvement. Encouraged by the interest of other researchers in our detailed results, we have also constructed a website (http://bilkent.edu.tr/~erel/dynlayout.html) so that one can easily download, for all relevant problem instances, the best layout in each period and the associated cost found by us.
