Syllabus

Calendar:

The calendar on the syllabus is the plan for this semester, this calendar reflects in detail what we actually get to cover in class and when.

…
3/9/2026: We reviewed grammars by looking at ascii math. Then we went over Chomsky Normal Form and Push-Down Automata. We finished by showing how to convert a grammar to a PDA. We will pick up next class showing how to convert PDA to a grammar.
3/2/2026: We reviewed NFAs, GNFAs, and Regular Expressions. We then looked at the Pumping Lemma for Regular Expressions and used it to show that certain languages are not regular (specifically those that require us to count and remember). We ended by introducing Context Free Grammars. We will pick up there next week.
2/23/2026: Snow Day The calendar will shift as needed. I will consider splitting the unit 1 exam into two or shifting the content of the exams to account for the missed days. I will let you know the details next week. You should be sure to study the material we have covered so far in preparation for next weeks quiz.
2/9/2026: Note that the Lecture 1 Slides were updated with an additional example of constructing a union. We finished the slides on DFAs and NFAs and started the slides on Reg. Exp.. We finished the first couple sections on those and will pick up next week with the Pumping Lemma.
2/2/2026: Today we went over the syllabus, the set of review slides, and the first two sections of the slides on Introduction to Finite Automata. Take a look at that material for next weeks quiz.
1/26/2026: Snow Day : I will adjust the calendar and we will get started next week.

Extra Credit: Turing Machine Class(Needs Revision!!!) Due before 5/12/2026 by 5:30pm
Extra Credit: Exploring the Infinite Due before 5/12/2026 by 5:30pm (We’re doing most of this in class, so for the extra credit you need to answer all the questions typed up neatly.)
