Data Structures are the paramount concern of this course. The principle
objective of the course is to help you learn how to design and analyze
a wide range of data structures.
The course covers data structures and associated algorithms.
Relationships among data structures, their utility in various
situations, and factors affecting their performance in algorithms will be considered. You will learn to analyze
the demands of algorithms, how to choose appropriate data structures,
and how to integrate data structures into algorithms.
Required: Data Structures and Algorithm Analysis in Java,
2nd Edition, by Mark Alan Weiss, Addison-Wesley, ISBN 0-321-37013-9
- Your favorite Java reference book -- here are some of mine
- Java in a Nutshell, 5th Edition by David Flanagan,
O'Reilly, 2005, ISBN 0-596-00773-6
- Thinking in Java, edition by Bruce Eckel, Prentice-Hall PTR, 2006, ISBN 0-131-87248-6. Available online at http://www.codeguru.com/java/tij/tij_c.shtml.
- Head First Java, Second Edition by Kathy Sierra and Bert Bates,
O'Reilly, 2005, ISBN 0-596-00920-8
- Data structures and algorithms with object-oriented design patterns in Java by Bruno Preiss, Wiley, 1999.
- Data Structures and Algorithm Analysis by Clifford
Prentice-Hall, 1996. This book has good coverage of data structures and
analysis in C++. It has excellent descriptions of a number of data
- Data Structures, Algorithms, and Applications in Java by
Sartaj Sahni, McGraw-Hill, 1998.
- Data Structures and Algorithms by Alfred Aho, John
Hopcroft, and Jeffrey Ullman, Addison-Wesley, 1983. This is one of the
all-time classics, written in Pascal.
- Fundamentals of Data Structures in C++ by Ellis Horowitz, Sartaj
Sahni, and Dinesh Mehta, 2006. Update of another classic.
- Abstract Data Types by Nell Dale and Henry Walker, D.C.
Heath and Company, 1996. A high-level view of data structures and
with no programming language specified. A very worthwhile and modern
text with an alternative viewpoint.
We will assume that you have mastered the material from
and CMSC 203.
We will not review material that has been covered in the prerequisite courses.
We do cover a few of the concepts from CMSC 202, but from a deeper
point-of-view. We assume prior experience with Java, review of Java will not be provided. For those of you who are not familiar with Java, please seek help from
Computer Science Help Center or TA.
Your grade for this course will be based on 4 programming projects, best 5 out of 6 homework assignments, 2 in-class exams and the final exam. These 3 exams are non-cumulative. The 4 programming projects are 40% of your final grade, 5 homeworks 10%, and 3 exams 50%.
All homework shall be submitted in hard copy in class of the due date.
No project or homework will be accepted past the due date resulting in zero points for that assignment.
Your semester average will be calculated according to the following formula
Semester Average = 10 * (sum of your points on best 5 HW) / (total possible points of best 5 HW)
+ 40 * (sum of your points on all projects ) / (total possible points on all projects)
+ 50 * (sum of your points on all exams ) / (total possible points on all exams)
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
Note that the due dates for the projects and the
dates of the exams are already set (q.v., the syllabus and project
policy page). Please plan your schedules accordingly.
Makeup exams will be given
only under the most dire circumstances (almost never).
Project regrade request must be submitted to the TA for your section within 1 week of a returned grade. In some unusual circumstances you may receive a low project score because of a single, simple error that results in many incorrect outputs or results in a compiler/linker error. The definition of "simple error" is determined by your TA. In such cases, your TA may (at his discretion) allow you to fix the simple mistake and have your project regraded. A 10 point deduction will be assessed during the regrade process. There will be NO regrades for homeworks.
Attendance and Readings
You are expected to attend all lectures. You are responsible for all
material covered in the lecture, 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.
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
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:
- Do not email program code. If you want me or the TA to
help you debug your code submit the code in the usual way, and then
send email about the problem. We will look at the submitted code. Please,
mail code to me or to the TA!
- Note that the Help Center does not offer help with code for this
- Please use your your UMBC account to send mail. This will remove
any ambiguity about who you are.
- Include a meaningful subject line, something like "CMSC 341
Project 2 question."
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
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.
