Algorithms Unlocked by Thomas Cormen, MIT Press, 2013.
Nine Algorithms That Changed The Future by John MacCormick, Princeton University Press, 2013.
Course Description: This course examines the applications of algorithms to the accomplishments of various programming tasks. The focus will be on understanding of problem-solving methods, along with the construction of algorithms, rather than emphasizing formal proving methodologies. Some of the algorithms we will study/implement include: searching, sorting, search engine indexing, Page Rank, pattern recognition: nearest neighbor, decision trees, neural nets, graph algorithms, error correcting codes, data compression, digital signatures, database algorithms, cryptographic hash functions, etc. Additionally, we will learn how to measure program performance, programming pitfalls, code optimization, advanced programming structures, etc. Prerequisites: CS206 and CS231. This is a Writing Intensive (WI) course.
January 17: First lecture
April 27: Last Lecture

April 30: Course Wrap up.
Punctual Attendance and active participation are
expected in every class. Anyone arriving later than 1:00p will be considered absent for that class. Participation includes asking questions,
contributing answers, proposing ideas, and providing constructive
comments. 30% of your course grade (see below) is based on attendance & participation.
As you will discover, I am a proponent of two-way communication
and I welcome feedback during the semester about the course. I am available to answer student questions, listen to concerns, and
talk about any course-related topic (or otherwise!). Come to
office hours! This helps me get to know you. You are welcome to
stop by and chat. There are many more exciting topics to talk
about that I won't have time to cover in-class.
stay in touch with me, particularly if you feel stuck on a topic
or project and can't figure out how to proceed. Often a quick
e-mail, or face-to-face conference can reveal solutions
to problems and generate renewed creative and scholarly energy. It
is essential that you begin assignments early.
All graded work will receive a grade, 4.0, 3.7, 3.3, 3.0, 2.7, 2.3, 2.0, 1.7, 1.3, 1.0, or 0.0. At the end of the semester, final grades will be calculated as a weighted average of all grades according to the following weights:
Labs & Written Work: 35%
Class Participation: 20%
Incomplete grades will be given only for verifiable medical
illness or other such dire circumstances. Please have any instances of medical illness or dire circumstances communicated to me thorugh your Dean.
Submission, Late Policy, and Making Up Past Work
All work must be turned in either in hard-copy or electronic
submission, depending on the instructions given in the
assignment. E-mail submissions, when permitted, should request
a "delivery receipt" to document time and date of submission.
Extensions will be given only in the case of verifiable medical
excuses or other such dire circumstances, if requested in advance
and supported by your Academic Dean.
No assignment will be
accepted after it is past due.
No past work can be "made up" after it is due.
No regrade requests will be entertained one week after the graded work is returned in class.
I encourage you to discuss the material and work together to
understand it. Here are some thoughts on collaborating with other
If you have any questions as to what types of collaborations are
allowed, please feel free to ask.
- The readings and lecture topics can be group work. Please discuss
the readings and associated topics with each other. Work
together to understand the material. I highly recommend forming
a reading group to discuss the material -- I will explore many
ideas and it helps to have multiple people working together to
- It is fine to discuss the topics covered in the homeworks, to
discuss approaches to problems, and to sketch out general
solutions. However, you MUST write up the homework answers,
solutions, and programs individually without sharing specific
solutions, mathematical results, program code, etc. If you
made any notes or worked out something on a white board with
another person while you were discussing the homework, you
shouldn't use those notes while writing up your answer.
- Under ABSOLUTELY NO circumstances should you share computer
code with another student, printed, electronic, or otherwise. Similarly, you are not
permitted to use or consult code found on the internet for any
of your assignments.
