Office Hours: By appointment only; (I'm *usually* free right after class, in my office 355 Altgeld Hall); see also the class Piazza site.

Textbook: Brualdi, "Introductory Combinatorics" (5th ed, although 4th ed should also be fine, I'll list the same problems from both editions).

Syllabus: Chapters 1-8 of Brualdi and special topics (time permitting)

Grading: Weekly assignments 15% (I will drop the lowest two assignment grades), Three Midterms 15%+15%+15%, Final Exam 40%. Grades 85%-100% guarantees an A- or above; 70%-85% guarantees B- or above; 60%-70% guarantees C- or above, 50%-60% guarantees D- or above etc. I will maintain grades online through Moodle.

Any missed midterm tests will be dropped and the final exam re-weighted accordingly, provided you have a doctor's note that indicates lack of fitness due to a medical issue. If a medical concern results in missed final exam, a make-up exam will be offered.

All homework is due on paper at the beginning of class. No late homeworks are accepted.

Test dates: All midterms are in class. Test 1: Friday Sept 23, 2022; Test 2: Wednesday Oct 26, 2022; Test 3: Wednesday Nov 30, 2022. Final exam: we will follow the non-combined final exam schedule : 11AM class=>8:00-11:00AM (Dec 14, 2022; 3101 Sidney Lu); 1PM class=>7PM-10PM (Dec 14, 2022; 245 AH)

Miscellaneous: I ask that you attend each class.

Reading the relevant sections before class to help facilitate learning through discussion, both between you and I, and between other participants and yourself. [Although probably most of the above requests seem like boilerplate for _any_ course, as combinatorics emphasizes learning through problem solving, doing the above is especially important.]

I encourage group work on assignments. You must acknowledge any collaborations, with a statement such as "I worked on problem 1 with XYZ and received help on problem 2 with ABC."

In addition, if you use books (other than the textbook) or online materials to solve the problems, you must cite their use. In all cases, you must write up your own solutions.

Such statements will in no way affect your grade, but are merely a matter of academic honesty. Failure to do so may lead to an academic integrity charge.
