The last day of classes of Computational Complexity. I'm both happy and sad. I'm happy because it was quite demanding, with loads of homework. But on the other hand, the subject is so cool and I'll certainly miss it.
I plan to buy Papadimitrou's book "Computational Complexity", but I must be sincere here and say that I'm quite scared of the sheer amount of typos and small errors that this book contains. Indeed if you ignore those errors, then the book is really good. I guess that it needs a beta-testing phase as it is feature complete.
