Course Information

Overview

CS 2112/ENGRD 2112 is an honors version of CS 2110/ENGRD 2110. Credit is given for only one of 2110 and 2112. Transfer between 2110 and 2112 (in either direction) is encouraged during the first three weeks. We cover intermediate software design and introduce some key computer science ideas. The topics are similar to those in 2110 but are covered in greater depth with more challenging assignments. Topics include object-oriented programming, program structure and organization, program reasoning using specifications and invariants, recursion, design patterns, concurrent programming, graphical user interfaces, data structures, sorting and graph algorithms, asymptotic complexity, and simple algorithm analysis. Java is the principal programming language.

Prerequisites

Very good performance in CS 1110 or an equivalent course, or permission of the instructor. If you are unsure whether CS 2110 or CS 2112 is the right course for you, please talk to the instructor of either course. Both courses cover similar material and satisfy the same requirements, but CS 2112 covers material in more depth and has more challenging assignments. It is aimed at computer science majors.

Texts

You are required to read the course notes posted on the web site. These will often contain more detail than what was presented in lecture.

There is a recommended textbook, which is also the textbook for CS 2110. It is useful especially for examples of how to implement various data structures.

See also the companion website for additional material.

Other Sources

These titles are on reserve in the Engineering library, Carpenter Hall.

The CS 2110 Java HyperText has many online learning aids and tutorial videos, including introductory videos on Java and Eclipse.

Piazza

We will be using Piazza as an online discussion forum. You are encouraged to post any questions you might have about the course material. The course staff monitor Piazza fairly closely and you will usually get a quick response. If you know the answer to a question, you are encouraged to post it, but please avoid giving away any hints on the homework or posting any part of a solution—this is considered a violation of academic integrity.

By default, your posts are visible to the course staff and other students, and you should prefer this mode so that others can benefit from your question and the answer. However, you can post privately so that only the course staff can see your question, and you should do so if your post might reveal information about a solution to a homework problem. If you post privately, we reserve the right to make your post public if we think the class will benefit. You can also post anonymously if you wish not to reveal your identity.

Piazza is the most effective way to communicate with the staff and is the preferred mode of interaction. Please reserve email for urgent or confidential matters. Free-ranging technical discussions are especially encouraged. Broadcast messages from the course staff to students will be sent using Piazza and all course announcements will be posted there, so check in often.

CMS

We will be using the course management system CMS for managing assignments, exams, and grades. Everyone who preregistered for the course should be entered, but if you did not preregister, you are probably missing. Please login here and check whether you exist. There will be a list of courses you are registered for, and CS 2112 should be one of them. If not, please send your full name and Cornell netId to the Administrative Assistant so that you can be registered.

You can check your grades, submit homework, and request regrades in CMS. Please check your grades regularly to make sure we are recording things properly. The system also provides some grading statistics. There is a help page with instructions.

Please do not repost course materials released on CMS publicly. These materials are intellectual property and are meant for participants in the course. They are not free to the public.

Announcements and Handouts

Announcements will be posted to Piazza. Homework and exam solutions will be available in CMS. Check frequently for new postings.

Assignments & Exams

There will be seven assignments, mostly involving programming but also some written problems. The first assignment will be done alone. The second and third will be done in pairs, which we will assign. The last four assignments are parts of a single project. These assignments will be done in pairs or triples, and you may choose your partner(s).

Unless otherwise specified, assignments may be turned in late with a penalty of 10% per day up to 5pm on the day of the first grading session following the due date (Wednesdays this year). Extensions may be granted in case of illness or other acceptable excuse; please contact the course instructor.

There will be one 1½-hour evening prelim and a 2½-hour final exam. Please check the schedule page for times and locations.

Your final grade will be based on your assignment and exam scores according to the following weights:

Regrades

Graded homework will be available on CMS. Graded exams will be available in the handback room, 216 Gates.

Homework regrade requests can be submitted electronically in CMS. Exam regrades should be handwritten and submitted to the course staff. Graded exams will be available in the handback room in Gates 216. Please include a description of the grading error with your regrade request.

Academic Integrity

The utmost level of academic integrity is expected of all students. Under no circumstances may you submit work done with or by someone else under your own name or share detailed proofs or code with anyone else except your partner. However, questions regarding general techniques or the requirements of the assignment are permissible.

You must cite all sources, including Internet sources. You must acknowledge by name anyone whom you consulted (excluding course staff). You may not give nor receive assistance from anyone else during an exam. You may not give any hints or post any material that might be part of a solution publicly on Piazza. If your question necessarily includes such material, post privately.

If you are unsure about what is permissible and what is not, please ask.

Special Needs

We will provide appropriate accommodation for students with special needs or disabilities. Requests for accommodation are to be made during the first three weeks of the semester and must be accompanied by official documentation. Please register with Student Disability Services in 110 Ho Plaza (Cornell Health Building), Level 5 to document your eligibility.
