Comp 220: Data Structures, Fall 2017

This syllabus is subject to change based on specific class needs, especially the schedule. Significant deviations will be discussed in class.

Logistics

Content

Data structures continues the study of abstraction and programming through a focused study of data structures, algorithms, and abstract data types. The primary focus of this course is the design and development of algorithms and programs using data abstraction and information hiding via abstract data types ADTs. Data abstraction is absolutely fundamental to good programming practice and the management of large scale problems and data sets. This course is designed to round out a student’s understanding of basic computer science concepts while strengthening the program design and development skills through continued use of a test-driven design methodology.

It is imperative that programmers and program designers be able to determine which of the many solutions available is the best for their specific task. Throughout the course, students will focus on to making solid quantitative and qualitative judgments about program efficiency and overall program design choices. Gone are the days when “it works” is a good enough assessment for the quality of a program.

Students will explore the ideas and concepts brought up in class and homework assignments during the weekly lab session. In addition to hands on exercises, lab sessions will be used to explore current, relevant research in computer science.

Topics

We will focus on chapter 5 and beyond from the text. This includes, but is not limited to:

The course textbook will be:

Other sources will be posted on this webpage as needed.

Programming Environment

This course utilizes the Code::Blocks ide and the GNU compiler for C++ development.

All programs written in this course are required to compile and run on a server running Ubuntu 16.04.3. All students will have access to the departmental server and thereby the above development tools. While development is not required in this environment, failure to properly port a program to the required environment could result in your program not compiling correctly at the time of grading. All software for this course is available free of charge and can be found on the web if students wish to install it on their personal machines.

Assessment

Assignments

The course workload is as follows:

Category Number Of Assignments
Labs 10
Homework 8–10
Projects 2
Exams 7

Homework assignments will always either precede a lab to prepare for it or follow a lab to complete it. Students are also encouraged to look at the textbook’s review questions, since the solutions are available online. There will be no dedicated midterm or final exam, but 7 exams spaced throughout the semester. Each exam will focus primarily, but not necessarily exclusively, on the material covered since the previous exam. The final exam will include a small number of cumulative questions, and I reserve the right to include at most one cumulative question on each of the other exams.

Workload

The weekly workload for this course will vary by student but on average should be about 13 hours per week. The follow tables provides a rough estimate of the distribution of this time over different course components for a 16 week semester.

Category Total Time Time/Week (Hours)
Lectures+Labs   4
Homework 48 3
Exam Study 16 1
Projects 48 3
Reading+Unstructured Study   2
    13

Grading

Lab and homework assignments are graded on a simple 3 point scale. Grades are marked with, in decreasing order, a check-plus, check, or check-minus. Your final grade for these two assignment categories is then based off the respective averages and determined by the following chart. Notice this chart lists the minimum average needed to achieve a particular letter grade.

Assignment Avg. (min) Letter Grade
2.8 A
2.75 A-
2.5 B+
2.25 B
2 B-
1.75 C+
1.5 C
1 C-
0.75 D
0.5 F

Your final grade is based on a weighted average of particular assignment categories. You can estimate your current grade based on your scores and these weights. You may always visit the instructor outside of class to discuss your current standing.

category weight
exams 45%
projects 25%
homework 12.5%
labs 12.5%
participation 5%

This courses uses a standard grading scale. Assignments and final grades will not be curved except in rare cases when its deemed necessary by the instructor. Percentage grades translate to letter grades as follows:

Score Grade
94–100 A
90–93 A-
88–89 B+
82–87 B
80–81 B-
78–79 C+
72–77 C
70–71 C-
68–69 D+
62–67 D
60–61 D-
0–59 F

You are always welcome to challenge a grade that you feel is unfair or calculated incorrectly. Mistakes made in your favor will never be corrected to lower your grade. Mistakes made not in your favor will be corrected. Basically, after the initial grading your score can only go up as the result of a challenge.

Schedule

The following tentative calendar should give you a feel for how work is distributed throughout the semester. Assignments and events are listed in the week they are due or when they occur. This calendar is subject to change based on the circumstances of the course.
