Arrangements and information here
General course arrangements (including information about the textbook) are detailed here.
For grades, please log on to Concourse.
In case you haven't yet had a chance to pick up a copy of the textbook, here is a copy of the first 30 pages or so.
Mathematical preparation: We will make much use of the basic mathematical language of sets and functions, and the techniques of induction and recursion. If you have taken a course such as Math 20630 (Introduction to Reasoning), you will already be fully familiar with everything we will use. If not, then you will be able to pick it up as the semester progresses. Here are some resources that you might find helpful.
Here is a document gathering together in one place all relevant graph definitions (it may evolve slightly as the semester progresses).
Here are the slides on the Gale-Shapley algorithm from Lecture 40.
Here are the notes on Catalan numbers from Lecture 37.
Here is an extract from Richard Stanley's book Enumerative Combinatorics in which he lists 66 different interpretations of the Catalan numbers. Here is an addendum to the list, in which he adds 136 more!
Here is a Tower of Hanoi applet.
Here are the notes on generating functions from Lecture 35.
Here are the slides on inclusion-exclusion from Lecture 31.
Here are the slides on Pascal's triangle from Lecture 26.
Here are the slides on basic counting problems from Lecture 25.
Here are the slides on theorems equivalent to the Konig-Egervary theorem from Lecture 24.
Here are the three matching problems from Lecture 19.
Here are the slides giving a brief history of the 4-color problem from Lecture 18.
Here are the three coloring problems from Lecture 16.
Here are the slides on the P versus NP problem from Lecture 12. Here's a link to the trailer for a (possibly very bad) 2012 movie about P versus NP.
Here is a page with information about Hamilton's Icosian game. Here's the Wikipedia page on the problem of the knight's tour.
Here is a link to information about Euler's paper on the Bridges of Konigsberg problem, from Lecture 10.
Here are the slides on Prufer codes from Lecture 9.
Here are the trees from Lecture 5.
Here is Wolfram's page on the Petersen graph, and here is the applet that allows you to move the vertices of the graph around. (From Lecture 4)
Here are the pictures from Lecture 1.
