If at any given time, all the assigned problems are solved, I will organize a barbecue for the class (and pay it).
Some rules: 1) If you already know a problem, disregard it; 2) You may discuss the problems with others who also do not know how to solve them, but eventually, it has to be your own solution. You can always ask me! 3) Do not only solve the problem, also think over how you will present the solution. If you do not have practice in this, you will learn it here.
