Applied Combinatorics , by Fred S. Roberts.
Homework is an important part of learning mathematics.
Part of your homework is to read the relevant sections of the textbook, as well as working on the homework problems. You should try to first read through each section before it is discussed in class. You are encouraged to discuss homework with other students in the class, but the homework solutions that you turn in for grading should be your own work. At the end of the semester your lowest homework score will be dropped and your total percentage on the rest will be rescaled to 250 points.
