Note that this schedule may change as the semester progress. Right now it is only up to Midterm).
- http://www.gametheory.net is an excellent resource,
where you can find other lecture notes and a
glossary of Game Theoretic concepts, and also can play some games!
Prerequisites: Theory of Probability (at the level of STAT 134), some basic real
analysis/calculus (at the level MATH 16A,B or MATH 104) and
linear algebra (at the level of MATH 54 or MATH 110).
- Homeworks: 20% of the total credit.
- Midterm Exam: 30% of the total credit.
- Final Exam: 50% of the total credit.
- There will be a total of 12 sets of weekly homework assignments, 6 prior and
6 after the midterm. Each carrying a total of 20 points. 10 best assignment scores
will be taken for the final grading.
- The assignments will be given in class on every Monday starting from September 9, 2013,
and it will be due on the Monday of the following week. Each assignment
set will be based on course materials covered in the (three) lectures in the previous week.
- Please submit your assignment to the GSI in your Section.
- Late submission of an assignment will NOT be accepted. If you
can not submit an assignment on time, don't worry about it, and try to do
well in the others. It will not count in your final grade since you
have two extra assignments anyway.
- Graded assignments will be returned by the GSI in the Section on
Monday following the due date.

for downloading the solutions of the assignments.
- Note there will be no assignment in the week of the midterm, that is, no assignment will
be given on Monday, October 21, 2013.
Midterm and Final Exam Policies:
- For both Midterm and Final Examinations you may bring a list of formulas, theorems with you and
your homework solutions, but no books, printed or photo copied materials
and/or hand-written, typed, of photo copied class notes will be allowed.
- No make up Final or Midterm will be given and no student may take the Midterm or Final earlier
- Here is a practice midterm and its
- Here is a solution to the Midterm.
- Here is a set of practice problems for the final.
- Regrading of homeworks or exams will only be undertaken in cases where you believe there has been a
genuine error or misunderstanding. Please note that our primary aim in grading is consistency,
so that all students are treated the same; for this reason, we will not adjust the score of one student
on an issue of partial credit unless the score allocated clearly deviates from the grading policy
we adopted for that problem.
- If you wish to request a regrading of a homework or exam, you must return it to the instructor or the
GSI with a written note on a separate piece of paper explaining the problem.
- The entire assignment may be regraded, so be sure to check the solutions to confirm that your overall
score will go up after regrading.
- All such requests must be received within one week from the date on which the homework or exam was made
available for return.
