Week 9

Started Formal languages. In the two lectures of this week, the amount of new terms we learned suprised me. Alphabet, languages, Kleene Star, all the operations of regular expressions, and even regular expressions as a topic of its own was new to me. I had to go through the lecture notes several times and do the proofs many times over and over in order to understand everything. The test on Friday I thought was ok, it was reasonable in difficulty for those who did the assignment and problem sets.
