Evaluation:

• Evaluation on each student will be done based on the following:
  1. Assignments - 40%
  2. Quiz - 5%
  3. Midterm Exam - 20%
  4. Final Exam - 30%
  5. Class Participation - 5%
• Note: the above evaluation scheme may change slightly during the course.

Assignments:

There will be about a half dozen assignments (worth 40% of the final mark).
• Assignment 1
• Assignment 2 (Solution)
• Assignment 3
• Assignment 4
• Assignment 5
• Assignment 6
Late assignments may be handed in, but there will be a penalty of 20% of the mark for assignments turned in less than one day late, and an additional penalty of 10% for each day thereafter.

Cheating Policy -- Cheating will not be tolerated in this course. Students are encouraged discuss things related to courses and assignments but the materials handed in must be his/her own. The maximum penalty for the first offense is for the assignment in question. For subsequent offenses may result in an automatic failure of the course and possibly other academic punishments.

Class Participation:

Students are strongly encouraged to attend all lectures and to participate in discussions during lectures. 5% of the final mark is assigned for good class participation.

Computer Accounts:

You are required to have a HEMOS account which can be used to access Unix and the Internet world.

Reading the News:

The newsgroup postech.class.cs516 has been set aside for course use. You can read and post news to this newsgroup using the Unix commands rn (or trn, xrn) and Pnews, respectively. Alternatively, you can use netscape to read and post news. If you wish to post or read articles, click (postech.class.cs516)

In this newsgroup you will find changes to the lecture schedule, clarifications to the assignments, etc. It is your responsibility to read this newsgroup on a regular basis. There is likely to be little information at the beginning, but more as the course progresses.
