Course Description
for Theory of Algorithms: CS 4440
TERM:
Spring 2016
ADVISORY REGARDING CONTRACT DISPUTE:
The California Faculty Association (the CFA) is a union that represents
all of the faculty at all twenty-three campuses of the
California State University (the CSU). The CFA is in the midst
of a difficult contract dispute with the managers of the CSU.
It is possible that the CFA will call a strike or other work stoppage
this term. I will inform the class as soon as possible of any disruption
to our class meeting schedule.

PREREQUISITES:
It is important that you be adequately prepared for taking this
course, CS 4440.
Check with me if you have not passed both:
- CS 3100 (Data Structures + Algorithms), or the equivalent, and
- MATH 2300 (Discrete Structures), or the equivalent.
COURSE OBJECTIVES:
The highest aims of this course are:
- to learn how to make the best possible algorithms,
- to know when it is impossible to make an algorithm any better, and
- to learn to choose an appropriate algorithm for a given problem.
One way to work toward those aims is to study algorithms and approaches to
algorithm design that are widely believed to be good for common programming
problems. At the same time, one should seek to understand how "good" should
be defined. Such studies are another goal of this course.
It is necessary that we know how to analyze the potential efficiency of an
algorithm using such tools as discrete mathematics, probability, and
statistics. We also need to study such abstractions as computational
complexity, reduction, non-determinism, and NP-completeness, in order to
better appreciate the limitations of computing machines.
It will be important that you read and write algorithms, and
practice doing the steps involved in their analysis.
REQUIRED TEXT:

COURSE COVERAGE:
As background and review:
- Chapter 2 (Basics of Algorithm Analysis), and
- Chapter 3 (Graphs)
As the main course content:
- Chapter 1 (Representative Problems);
- Chapter 4 (Greedy Algorithms), excluding sections 4.3, 4.7-4.9;
- Chapter 5 (Divide and Conquer), excluding sections 5.5-5.6;
- Chapter 6 (Dynamic Programming), excluding sections 6.5 & 6.10;
- Chapter 7 (Network Flow), excluding sections 7.4, 7.6, 7.11, and 7.13;
- Chapter 8 (NP and Computational Complexity);
- Chapter 9 (PSPACE);
Possibly we'll make some adjustments to the list above.
TESTS & GRADING:
Your course grade will be based on a class participation component (=PC) and a
test component (=TC).
Satisfactory class participation means satisfactory work on assigned problems,
a good attendance record, evidence that you are staying current with the
reading assignments, and satisfactory contributions to in-class discussions.
There will be class discussions of problems. I will sometimes require you to
work on problems in advance and turn in notes that "show your work." (similar
to homework assignments, but they will not be graded in the traditional
sense.) Some problems I assign may involve programming, but not long programs.
There will be two in-term exams and a comprehensive final exam.
The test component of your grade will be calculated this way:
TC = [ Max(E1,F) + Max(E2,F) + F ] / 3
Where E1, and E2 are your grades on the in-term exams, and F is your grade on
the final exam.
Your course grade will be
TC + PC/10
This means, for example, if your test component works out to a D, but you get
100% on participation, your course grade will be a C.
MISSED EXAMS AND LATE ASSIGNMENTS:
I will give no make-up, late or early exams.
Get started early on assignments. That way, if you run into difficulty, you
can seek help in class and/or office hours in a timely fashion.
You must turn in work on assigned problems when due . Lateness will
count heavily against your participation score. However keep in mind that you
are assigned to turn in evidence that you worked on the problems. So work on them, and whether or not you solve them completely, turn in (on time) something that shows your work.
To "survive" in a class like this, you may need to put aside "foolish pride,"
stubbornness, and/or shyness. If you find you are not making good progress in
the course, please seek help from me promptly. You may speak to me after
class or during my office hours. You may send me a message by e-mail. You
are entitled to get help this way. Please don't subvert your chances of
success by continuing to "spin your wheels" until it is too late.
We can have class discussions about exam dates and assignment due dates.
I may be willing to change some of these dates.
If you want a change in the schedule,
please bring this up (in class, preferably) as soon as possible, and not at
the last minute. (It's usually a good idea for class members to try to work
out some consensus among themselves before bringing the subject up with me.)
Again, if you cannot finish an assignment on time please turn in whatever you
have done. Then it will be possible to get some credit instead of
no credit.
PARTICIPATION:
College is not for everyone. Some people who go to college don't do well in all their classes. Sometimes they fail classes. Sometimes they decide to change majors
to something more do-able. Some people who start college don't graduate.
College demands that the student learn actively and independently.
Naturally college makes demands on instructors too. I want you to get as much
as possible out of the course. I hope to be accessible and helpful to you.
Read and study everything I assign as soon as possible. Read difficult
material more than once! Attend all classes. Pay close attention. Take
notes to help you think about things and remember things. Review your notes
before each class. Get started on assignments early. Do a little work each
day so that work never piles up. Bring your questions and problems concerning
assignments to class each day.
Finish assignments and reading on time. Be an active learner.
Do what you can to keep class
discussion productive. Reply to questions. Ask questions and
make remarks if you feel you have something to add or if you want me to
explain something better.
RESPONSIBILITY FOR YOUR OWN WORK:
Sometimes it can be difficult for the student to figure out the difference
between 'cheating' and 'working smart.' Here is some guidance:
Assignments: When your purpose is to clarify the meaning of the
directions I have given for an assignment you may discuss those directions
with other people, including your classmates, as much as you like. You may
also freely discuss the relative merits of various general approaches to
designing and engineering solutions to an assignment.
You may use ideas, algorithms, or segments of program code from
- any printed material available for student check-out in our library,
- our course text, or
- any programming textbooks to which you have access.
You are permitted to share such material, as described in 1-3 above, with
other members of this class.
You may ask me for help and hints on assignments. I prefer that you ask
questions in class, so that everyone has a chance to benefit from the
discussion.
On the other hand, until the time comes for us to discuss problems in class
together,
- You must not give or accept any other kind of help.
- You may not allow any part of a solution you compose (make up) for
a homework assignment to be communicated to another member of the class
or allow such material to be communicated to you.
- A corollary to the point above is that one member of the class may
not look at the homework of another member of the class, whether
on paper or on a computer screen.
Exams: You must write your exams/tests with no discussion or help from
anyone. The one exception is that you are allowed to come forward and ask me
to clarify the meaning of a test question, if you wish. It will be up to me
to decide how to answer, or whether to answer at all. I will tell the class
any new information that arises from such an exchange.
Penalties: If there is compelling evidence that an assignment or exam
was not done according to the above criteria, I will withhold credit for the
assignment and/or lower your course grade, as I deem appropriate.
