for the course is the combination of the exam grade
(two midterms; no final) and the homework grade
- Theoretical homework is collected on the due date, before class.
- Applied (implementation) homework should be emailed to both TA and the instructor by the deadline (specific for each assignment).
- No late homework will be accepted without instructor's
permission (a permission must be requested at least 24 hours
before the due date).
- You may work with other people on the theoretical
homework, but you must each write up your solutions separately
(without any written aid). If you work with other people, indicate
who you worked with on your solution.
- You must work alone on the applied (implementation) homework. Do not discuss the problem
with anybody (except me), do not search for a solution online, do not use any written material
when writing any part of the code (for example, no copy-paste, no open textbook
when writing code, no reediting of an old source file from an old project, etc).
- All tests are closed book. No text
or notes, no scratch paper allowed.
