I am taking up two MSCS subjects this semester. One of which is CS240. It deals with Theory of Computation and is a sequel of an undergraduate course, CS133 or Automata Theory. The first set of lectures is a recap of the latter.

One of my classmates is my byte, UP Cursor term for a senior buddy. We reminisce the good old days of color-coded “yellow” pad-long problem sets of Ma’m Becca. We listed alphabets and strings and drew concentric circles, pumping stacks and parse trees. Yet, at some “state”, we cannot “recognize the language” our teacher speaks of. Furthermore, this seasons comes Greek to me as the notations with inverted letter ‘A’ and letter ‘E’ hunt me. They are not aesthetically nice at least, for me.

I need to purchase Sipser’s book so I can review such topics. Just like what our instructor’s line, “Magagalit ang Panginoon” if I forgot CS 133. I learned from Kaye that Sir Henry, our teacher, gives 4-item examination. I fear that he will ask us to prove or disprove something. It’s all or nothing. It’s like that you really know or you don’t know. In 3 weeks time, the dreaded midterms examination will come.

As of now, I’m enjoying while learning so to voluntary exit is not my type. I’m living in a teleserye ng automaton na buhay. This is PDA: Push Down Automata Season 2.
