Welcome back! We will continue our POW. Starting from this semester, we will have a new set of rules. First of all, the problems will be posted on every Friday 3PM. (Note that we now have a tea time every day at 3PM.) The problem will be still posted on the blackboard in the room 1401, E6-1 bldg as well as on this website. 

We will also revise our way of selecting winners of the semester. At each week, students will earn points.

• +2 if the submitted solution seems reasonable. (meaning: good try, it may be correct but I don’t have enough time to check it carefully)
• +3 if the submitted solution is correct,
• +4 if it was selected as the best solution. (meaning: correct and well written)

At the end of each semester, we will select the 1st, 2nd, and 3rd students as we did in the previous semester.

How to submit your solution: read the “rules” section.
