Office hours: Tuesdays 4-4:30, Wednesdays 9-9:30am, in 224 Illini Hall
Please come to the regular office hours unless you have a class at the same time. If you want to come to an office hour but have a class at the same time, e-mail me (at least a day in advance, but preferably sooner) and I will most likely be able to meet you at a different time.

Here is our syllabus.

Homework remarks: Make sure to do the Exercises, not the problems from the section entitled Skills Check. Explain your solutions well.

Homework solutions:
solution 3
homework 7 and worksheet from Friday 10/05
solution to homework 11
solution to homework 12

Probability and Number theory chapters for your personal use.
You can get a printed copy of the number theory text from me (if you didn't get one already).

Note: For the section on number theory, you will need a 4 function calculator (one that only has addition, subtraction, multiplication and division). It can have a square root button, but it shouldn't be any more fancy than that.

HW14, due Wednesday 12/5

Do the following exercises from Chapter 5:
2
5 (in part (b), use classes with width 2 metric tons per person)
6
12 (in part (a), make a histogram with classes of width 10 instead of stemplot. We didn't talk about stemplots in class.)
14
Note: The rest of the exercises are about standard deviation and normal distributions, which will be covered in class on Monday.
30 a) and b) only (in part (b), use the formula for sample variance)
32
34 You might want to read p. 197 and 198 first.

70 - part a) only. First create a table with X's similar to the one on page 103 (include this in your solution), and then solve the problem.
72

HW2, due Wednesday 09/05
Construct an example of a graph with assigned edge-weights (different from the examples in the book) for which the Nearest Neighbor algorithm finds a Hamiltonian circuit, but not an optimal (cheapest) one. Try to make your graph small and simple. Write down the circuit that the Nearest Neighbor algorithm finds. Write down another, cheaper circuit.

Do the following exercises from Chapter 2:
2, 20, 40a), 48, 52, 54

HW1, due Wednesday 08/29
Do the following exercises from Chapter 1:
4,
5: in (a) replace "C and D" with "B and D" and in (b)(ii), replace "C to F" with "C to E",
8, 12, 24, 32,
34: In this exercise, add only copies of edges that are already in the graph. Try to add as few as possible.
38, 40, 48

Do the following from Chapter 2:
6, 8
In addition, find a graph (different from those mentioned in the book) that doesn't have a Hamiltonian circuit.
