To take this class you must have taken:
C155
with a grade of C or better.
This course covers the basics of randomized algorithms,
parallel algorithms, distributed algorithms, algorithms related to the theory of NPcompleteness,
and approximation algorithms. Randomized algorithms are algorithms which make use of a random number generator.
For instance, one fast way to check if a number is prime makes of such a generator. Parallel algorithms
are algorithms which are designed to be partitionable with minimal overhead
among many processors who share a global clock. Sorting networks to sort lists on polynomial processors in logarithmic
time are examples of this. Distributed algorithms are algorithms designed to work on multiple processors which don't
share a global clock. An example situation might be to get an algorithm to get a bunch of computers on a network
to agree on a common value. NP problems are languages with polynomial time proofs of membership. For instance,
given a potential factorization of a number we can in polynomial time check whether it is correct. NPcomplete problems are
problems in NP to which any other problem in NP can polynomially time reduced. We will consider different algorithms for during this
kind of reduction. Approximations algorithms are usually efficient algorithms which approximately solve some optimization
problem which is not known to have a efficient solutions. For instance, one might have an algorithm which approximately finds
a traveling salesman tour. In addition to these algorithms, we will also go over the computer algebra algorithms neccessary to do basic
cryptographic protocols such as RSA. By the end of this course, you should be able to code one example of a randomized algorithm,
parallel algorithm, distributed algorithm, a polynomial time reduction, an approximation algorithm, and a computer algebra algorithm. For each of
these types
of algorithms, by the end of this course you should be able to do problems to analyse its runtime performance and correctness.

Grades will be calculated in the following manner: The person or persons with the
highest aggregate score
will receive an A+. As this is a graduate class the material will be harder, and so I
will make a slightly more lenient curve than typical for an undergraduate class.
The lowest scoring person with a score above 60 will be
the cutoff for a B. That is,
that person will receive a B, but no one below him will. The region between
this high and low score will be
divided into five equalsized regions. From the top region to the low region,
a score falling within a region
receives the grade: A, A, B+, B, B. If the boundary between an
A and an A is 85, then the score
85 counts as an A. Scores below the lowest B but above 50 receive the grade C.
Those below 50 receive the
grade F.
If you do better than
an A in this class and want me to write you a letter of recommendation, I will generally
be willing provided
you ask me within two years of taking my course.
Be advised that I write better letters if I know you to some degree.
Links to the current list of assignments can be found on the left hand frame of the
class
homepage. After an assignment has been returned a link to its solution (based on the best student
solutions) will be placed off the assignment page. Material from assignments may appear on midterms and
finals. For homeworks you are encouraged to work in groups of up to three people.
Only one person out of this group needs to submit the homework assignment; however,
the members of the group need to be clearly identified in all submitted files.
Homeworks for
this class will be submitted and returned completely electronically. The written and
programming parts of an assignment are submitted by clicking on the submit homework
link
for your section on the left hand side of the homepage and filling out the online
form.
Hardcopies or email versions of your assignments will be rejected and not receive
credit. Homeworks will always be due by the start of class on
the day
their due. Late homeworks will not be accepted; however, your low homework score will
be
dropped.
When doing the programming part of an assignment please make sure to adhere to the
specification given as closely as possible. Names of files should be as given, etc.
Failure to follow the specification may result in your homework not being graded and
you receiving a zero for your work. In addition, you should make sure your code
conforms
with the Departmental Java Coding Guidelines. This will be worth one point on every assignment.
The written part of each homework should be typeset in LaTeX. Links to where one
can obtain LaTeX can be found in the Text and Links section above.
The midterms will be during class time on:
Feb 20 and Apr 12
.
The final will be: Monday, May 22 from 5:15pm7:30pm.
All exams are closed book,
closed notes and in this classroom. You will
be allowed only the test and your pen or pencil on your desk during these
exams. Beeper or cellphone interruptions will result in immediate excusal
from the test. The final will
cover material from the whole quarter although there will be an emphasis on
material after the last midterm. No make ups will be given. The final exam
may be scaled to replace a midterm grade if it was missed under provably
legitimate circumstances. These exams will test whether or not you
have mastered the material both presented in
class or assigned as homework during the quarter. My exams usually consist
of a series of essay style questions. I try to avoid
making tricky problems. The week before each exam I will give out a
list of problems representative of the level of difficulty of problems the
student will be expected to answer on the exam. Any disputes concerning
grades on exams should be directed to me, Professor Pollett.
If you believe an error was made in the grading of your program or exam, you
may request in person a regrade from me, Professor Pollett,
during my office hours. I do not accept email requests for
regrades.
A request for a regrade must be made no more than a week after the homework or a midterm is
returned. If you cannot find me before the end of the semester and you would like to request a
regrade of your final, you may see me in person at the start of the immediately following
semester.
Plagiarism on homework or cheating on tests
will result in appropriate academic disciplinary action being taken. You should
not discuss or share code or problem solutions between groups!
Information on the university policy governing academic dishonesty can be
found at http://www2.sjsu.edu/senate/S0412.htm.
At a minimum a 0 on the assignment or test will be given. A student
caught using resources like Rentacoder will receive
an F for the course and be referred to University for disciplinary action.
The campus policy to ensure compliance with the Americans with Disabilities Act is:
"If you need course adaptations or accommodations because of a disability, or if you need special arrangements in case the building must be evacuated, please make an
appointment with me as soon as possible, or see me during office hours. Presidential Directive 9703 requires that students with disabilities register with DRC to
establish a record of their disability."
