Cancelation 2008

The 18th IPCCC 2008 was canceled, due to lack of registrations. Only six participants registered, and not all participants had an interest to play the tournament with such a reduced number of players. One reason for potential participants with family commitments was the scheduling between Christmas and New Year. Another possible reason might be the general loss of interest of amateur programmers to play the strong commercial programs almost not represented by their author.
