Please Note the schedule changes for the couple of lectures lost because of the snow.

Especially, you should note the date change for the exam! In the event of snow cancellation on 2/27, the exam will be pushed back to 3/6.

Course Description

The course is titled "Data Structures", and we will deal with them in some depth; the primary course objective is to learn to design amd analyze the performance of a number of "classical" data structures.

The course covers data structures and associated algorithms. We will study the relationships among data structures, their utility in various situations, and factors affecting their performance. You will learn to analyze the time and space complexity of algorithms, how to choose appropriate data structures, and how to integrate data structures into programs.


Required: Data Structures and Algorithm Analysis in C++, 2nd Edition, by Mark Alan Weiss, Addison-Wesley



The course prerequisites are CMSC 201, CMSC 202, and CMSC 203. You are expected to have some proficiency in program design using C++. We will not review material that has been covered in the prerequisite courses. A part of the course discusses a few of the data structures from CMSC 202, but from a deeper point-of-view. A few advanced C++ topics such as templates and exceptions will be reviewed. 


Your grade for this course will be based upon 5 projects, 2 in-class exams and the final exam. The projects are worth 40% of your grade, each project weighted equally. Each in-class exam is worth 20 percentage points; the final is worth 20 points. Note that the due dates for the projects and the dates of the exams are already set (q.v., the syllabus and project policy handout). Please plan your schedules accordingly.

If you work and have planned travel time around an exam, you need to notify me in advance. If you miss an exam for any reason other than illness requiring medical attention or for an emergency, you will receive a zero on the exam.
An "emergency" is "a situation or occurrence of a serious nature, developing suddenly AND unexpectedly, and demanding immediate action.

Your final letter grade is based on the standard formula:

0 <= F < 60, 60 <= D < 70, 70 <= C < 80, 80 <= B < 90, 90 <= A <= 100
These levels may be adjusted slightly in your favor, but grades will not be ``curved'' in the conventional sense.

Your grade is given for timely work done during the semester; incomplete grades will only be given for medical illness or other such dire circumstances. Please note that "timely" means "submitted on or before the announced due date". In particular, due date extensions for projects don't happen.

Attendance and Readings

You are responsible for all material covered in the lectures, even if it is not in the textbook. You should keep up with the assigned readings during the semester. Some reading material will be distributed through the course web page. You are responsible for the material in the readings, even if it is not covered during lecture.

PowerPoint slides are usually available in advance of the lectures; they are there to support your preparation for class. They are not a substitute for lecture attendance. So, even though I do not take attendance and you are not required to attend lectures, you run a very high risk of severely damaging your grade by skipping them.

You must study to do well in this course. It will not be enough to attend lectures and do the homework. As advanced undergraduates, you will be responsible for learning material that is not necessarily covered in lectures. A prime learning requirement is that you contribute to class discussions and raise questions about the course material.

You should plan on spending at least 12-15 hours per week outside of the classroom on preparing for and reviewing lecture materials and the projects. Also, if the only code you write in here this semester is for the projects, you can reasonably expect a "C" in the course. To learn this material, you really need to experiment with it. That means writing demonstration code for your individual learning.

BlackBoard Discussion Board

A BlackBoard site has been created for this course. This site is used primarily to support discussion boards, but announcements are also posted there. A discussion board will be established for each programming project. Students are encouraged to post general project questions, answer questions posted by other students or just browse the discussion board to find answers to project questions. Your instructors and TAs will also be posting questions and answers. Your questions may be posted anonymously. Other discussion boards for topics such as general C++ questions will also be established. The course BlackBoard is accessed by logging on to and clicking on the BlackBoard tab at the top of the page.

Contacting Me or the TAs

Please feel free to visit me or the TAs during our office hours. If you can't make it during the regular hours, please ask for an appointment. We will do everything we can to be available to provide help with this course. Office hours, phone numbers and other contact information is available on-line. If you need to contact any of the course staff outside of lecture and office hours, email is much better than the telephone. You should, however, observe the following etiquette:

Academic Integrity

Cheating in any form will not be tolerated. Instances of cheating will be reported to the UMBC Academic Conduct Committee. These reports are filed by the Committee and can be used for disciplinary action such as a permanent record on your transcript. Academic honesty is absolutely required of you. You are expected to be honest yourself and to report any cases of dishonesty you see among other students in this class. Reports of dishonest behavior will be kept anonymous.
Further details on honesty in doing projects for this course are on-line at the Project Policy link.

Students are welcome and encouraged to study together for exams, but examinations are to be your own work -- not your neighbor's and not your notes. All exams are closed-book, closed-notes. Only pencils (or pens) and erasers are permitted in the exam room unless otherwise indicated. Scratch paper is provided to you, as needed. Having any other materials in your possession during an exam will be taken as evidence of cheating and dealt with accordingly.
