====== CMP 601: Algorithms and Theory of Computation (2020/1) ======

//Somebody once asked John Hopcroft about the problem of P and NP. He answered: "On Tuesdays, I try to prove that they are equal, on the rest of the week - that they are different." I believe that he has reduced the time to try to show that they are equal to Sunday afternoons.//
