Grading

The course consists of three main parts, covering respectively functional, concurrent, and logic programming. Evaluation for each part includes a programming assignment and a partial exam.

For functional programming, we will use Haskell and Oz. For concurrent programming, we will use SALSA and Erlang. For logic programming, we will use Prolog and Oz. You must understand both languages to be prepared for exams. However, you can choose any of the two supported programming languages per paradigm for programming assignments, or even your own (but do not expect help from the instructor or TAs if you choose your own). Programming assignments can be done either individually or in pairs. Do not show your code to any other group and do not look at any other group's code. Do not put your code in a public directory or otherwise make it public. You are encouraged to use the Submitty Discussions page to post questions so that other students can also answer/see the answers. There will be three grace days for late submissions throughout the semester, to be used in any combination of PAs, e.g., PA1 may be one day late and PA3 may be two days late, as long as PA2 was submitted on time. Late assignments beyond the three day grace period will receive a grade of 0.

Students may use for reference during exams: physical textbooks, printed course slides, and one personal crib sheet. No electronics will be allowed. All exam answers must be your own. Exam grades may be curved.

We will use the following weighting scheme for grades: The best two programming assignments will have a total grade weight of 40% (20% each), while the third one will have a weight of 10%. We will use the same weighting scheme for partial exams: the best two exam grades will be worth 40% of the total grade while the third one will count for 10% of the total grade. Final letter grades will then be assigned as follows:
