Extra lecture this Friday 1-2:30

With all the holidays causing us to miss lectures, I'm going to have to take one extra lecture if I'm going to get through the material you need for the last HW...  So, we'll have an extra lecture this Friday Feb 23 at 1-2:30 in ARMS 155 (same time and place as normal).  I hope that everyone can make it ... it will be the start of our section on "routing games", which is a particularly fun topic I think.
