Dave Schmidt's Intro to Discrete Structures Page

Welcome to Intro to Discrete Structures. The purpose of this page is to make certain resources
available and keep you up to date with everything that is going on in the course.

Here  is a link to a paper I wrote that discusses some of the potential pitfalls that arise in trying to
solve counting problems. It refers to some of the same examples we will discuss in class.


Our final exam will take place on Thursday, December 16 from 3 - 6 PM in West Hall Auditorium.

No books, notes or calculators are allowed. The final exam will contain all of the formulas included on
the previous three exams.

There will be a review class conducted by Dr. Schmidt on Wednesday, December 15 from 1:00 - 2:30 PM in Darrin 324.
Here are some
  practice problems. Note that the document has been submitted for scanning, but the link may
take some time to become active.

Dr. Schmidt will also have office hours on Thursday, December 16 from 10 - 11 AM.


The final exam will consist of two parts:

        The first part will consist of three problems, all of which you must solve. These problems will be worth
        15 points each, for a total of 45 points.

        The second part will consist of four problems. You must choose three of the four to solve.  
        You will need to indicate on the front of the exam which problem you do not want graded.
        These problems will be worth 20 points each, for a total of 60 points.

        Thus, the final exam is worth 105 points just like all of our other exams.


Below is a list of topics to be potentially covered on the exam, with textbook citations. Since we didn't necessarily

discuss every section in its entirety, the class notes are the best guide to the exact material covered.
