This course will cover functional and logic programming, concepts of programming language design, and formal reasoning about programs and programming languages. The following are the course learning objectives:
Through taking this course, students will learn the tradeoffs of imperative vs. nonimperative programming languages, issues involved in designing a programming language, the role of formal semantics and typesystems in reasoning about programs and languages, and proof techniques related to programming language design.
The course is open to Ph.D. students and Masters students. Interested undergraduates should see the instructor for permission to take the course.
Prerequisites: Discrete Structures (CS 3305/5333 or equivalent), Algorithm Analysis and Data Structures (CS 3345/5343 or equivalent), Automata Theory (CS 4384/5349 or equivalent). A solid background in all three of these areas will be heavily assumed throughout the course!
STUDENTS MUST ATTEND AT LEAST TWO OF THE FIRST THREE CLASSES. IF YOU MISS MORE THAN ONE OF THE FIRST THREE CLASSES, YOU WILL NOT BE PERMITTED TO TAKE THE COURSE. The first three classes will cover functional programming in the OCaml programming language, which will be the basis for most of the rest of the course. To better understand the inclass OCaml demos, you should do the following as preparation:
If you can't get OCaml to work on your personal machine, you can use OCaml on the UTD CS Department Linux servers. To do so:
You can install your own local version of SWI Prolog or you can access the version installed on the UTD linux servers as follows:
Homework (25%): Homeworks will be assigned approximately once per 1.5 weeks, and will consist of a mix of programming assignments and written assignments. Programming assignments will be done in OCaml, Prolog, or possibly Coq. Written assignments will typically involve discrete math proofs. Homeworks must be turned in at the start of class (i.e., by 1:05pm) on the due date. No late homeworks will be accepted.
Quizzes (15%): On indicated assignment due dates (see the course schedule below), students will solve one or two problems individually at the start of class as a quiz. The quiz problems are essentially extra homework problems solved individually in class without the help of the internet or collaboration with other students. The quizzes will be closedbook and closednotes.
Midterm (25%): There will be an inclass midterm exam in class on Tuesday, March 10th. The exam will cover functional programming, operational semantics, denotational semantics, and fixpoints.
Final (35%): The final exam for the course is scheduled for TBA. The exam will be cumulative, covering all material in the course. Students will have 2 hours and 45 minutes to complete it.
Students may work individually or together with other students presently enrolled in the class to complete the assignments, but they must CITE ALL COLLABORATORS AND ANY OTHER SOURCES OF MATERIAL that they consulted, even if those sources weren't copied wordforword. Copying or paraphrasing someone else's work without citing it is plagiarism, and may result in severe penalties such as an immediate failing grade for the course and/or expulsion from the computer science program. Therefore, please cite all sources!
Students may NOT consult solution sets from previous semesters of this course, or collaborate with students who have such solutions. These sources are offlimits because such "collaborations" tend to involve simply copying someone else's answer to a similar homework problem, which does not prepare you for the quizzes and exams.
The course has no required textbook, but we will make use of several online references:
