ENGG 2440A: Discrete mathematics for engineers

The Chinese University of Hong Kong, Fall 2014

Recent Announcements

Course Description

This course is about mathematical models and techniques that are helpful for describing, analyzing, and solving problems in computer science. There will be much emphasis on proofs and rigorous reasoning.

To be successful in discrete mathematics, you will need to go beyond "recipes" for calculating answers and learn how to argue convincingly that your solution to a given problem is sensible.

Tutorials and homeworks

Homeworks will be issued every other week according to the following schedule:

Come to tutorial prepared. Your participation and the quality of your presentation will count towards your grade. If you cannot make it on any particular week, let your TA know in advance.

You are encouraged to collaborate on homeworks, but you must write up your own solutions and list your collaborators on the solution sheet. You will hand in the solutions to your TA at the beginning of Friday tutorial. No late submissions will be accepted. Please read the CUHK policy on honesty in academic work.
