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.
