Hi guys, There will be a team practice session on Tuesday September 29 starting at 14.15 in Stibitz-123. I will set a virtual contest on the TJU (http://acm.tju.edu.cn/toj/) online judge with a number of old problems from the NCPC (the same contest we are going to next Saturday). If you are interested, but cannot make it at 14.15, then you are welcome to show up at a later time. Similarly, if you don't want to stay for five hours, then feel free to leave earlier. I will let the contest run for say 10 hours, so you will have plenty of time to look at the problems. Best, Mark
