Title: CS 6371: Advanced Programming Languages
Course Registration Number: 27948 / 003641
Times: TR 1:00–2:15
Location: CB3 1.302
Instructor: Dr. Kevin Hamlen (hamlen AT utdallas)
Instructor's Office Hours: TR 2:15–3:15 in ECSS 3.704
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 formal, highassurance software validation.
The course is open to Ph.D. students and Masters students. Interested undergraduates should see the instructor for permission to take the course.
Prerequisites: Algorithm Analysis and Data Structures (CS 3345/5343 or equivalent), Automata Theory (CS 4384/5349 or equivalent). A solid background in each of these areas will be heavily assumed throughout the course!
The first three classes are extremely important for succeeding in the remainder of the course; students are therefore urged to participate in the course from the start, ideally by attending the first three classes in person if possible, or by streaming the lectures remotely if necessary. These initial classes will cover functional programming in the OCaml programming language, which will introduce many concepts assumed throughout 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:
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 implemented in OCaml or Prolog. 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. To help students prepare for the next assignment, homework solutions will typically be revealed on each due date. Therefore, 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 Thursday, March 10th. The exam will cover functional programming, operational semantics, denotational semantics, and fixpoints.
Final (35%): A final exam for the course will be held on Thursday, May 12th from 2:00–4:45pm. 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 or reverseengineering 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:
