We have already decided to put some life and death problems on our blog, but from now on we will also check and teach the solutions for you guys. Let's start with four problems per a week. Try to solve these problems and if you are interested in the solutions, join us when we check the problems. Usually it will be a week later, but for exact date and time, I will let you guys know few days before the life and death lecture. All you have to do is to solve the problems and join to the BIBA room on KGS.
