1.2 Course Administration

Prerequisites

CS 241, CS 288.

Textbook

T.C.Cormen, C.E.Leiserson, R.L.Rivest, and C. Stein. ``Introduction to Algorithms'', 3rd edition, MIT Press, ISBN-10 : 0262033844, (ISBN-13: 978-0262033848). We abbreviate it in class as CLRS.

CourseWork:

4 exams (including the final); Programming MiniProject (aka MP) .

Grades:

1000 points = MP(160)+ Ex1 (125) + Ex2 (245) + Ex3(125)+ Ex4 (345)

MP

A programming mini-project (MP) with 3 options each one worth 120 points. A student may submit one or two options; both options must be submitted together (all files in one archive) in ONE email message per Handout 2 AND RECEIVED BEFORE NOON-TIME of the date specified in the Calendar. On the sum of the grades of the options submitted lateness points are applied. 30 lateness points deducted at noon-time of due date and every noon-time thereafter. A 0-60 grade for the resulting grade is accounted as 0; an over-60 grade is cut-off at 160 points. Over-160 points are excess points.

PS

Approximately eight problem sets PS1-8 will be periodically posted along with their solutions. Exams 1 and 3 may draw from these problem sets.

Exams

Dates in Course Calendar and in classroom unless noted otherwise. Exam1 and Exam3 are closed-everything. Exam2 and Exam4 are open-textbook only; you may bring a hard-copy of the textbook but you are not allowed to borrow one during the exam. For the final, you may also bring in class a clean copy of Handout 4 on red-black trees in addition to the textbook. Exam1 is on Wed Sep 27, 45min, 125 points. Exam2 is on Mon Oct 23, 75min, 245 points. Exam3 is on Wed Nov 15, 45min, 125 points. Exam4 is on ??? Dec ??, 2hrs, 345 points.

Section 2.2 of the previous page contains a tentative list of topics that is intended to be covered in class. The code $Ti$ refers to a topic. A topic may spread over one or more lectures. The code $\mathrm{AL}i$ refers to the ACM Computing Curricula 2013 topic description code. In parentheses, we provide an approximate number of hours per topic. Hour coverage may change depending on circumstances (eg. class pace, weather). Minimum time requirements of the topics covered are. AL1 (basic analysis):4, AL2 (algorithmic strategies): 6, AL3 (fundamental data structures and algorithms):12, AL4 (basic automata, computability and complexity) optional:2, AL7 (advanced data structures, algorithms and analysis): elective, DS3 (proof techniques):1, DS5(graphs and trees):1.

MISSING

If you miss a class, it's up to you to make up for lost time. If you miss an exam you MUST CONTACT the Dean of Students (DOS) within 2 working days from the day the reason for the absence is lifted with all necessary documentation. The maximum accommodation period will be the number of missing days to the exam date: it is imperative then that you contact DOS even before the 2 working day period has expired if the accommodation period would be shorter. For Exam1, a DOS approval will get you a scaled Exam2 grade for Exam1. For Exam3, a DOS approval will get you a scaled Exam4 grade for Exam3. No MP extensions for any reason, medical or otherwise; you have 3 months to submit it: SUBMIT EARLY.

Grading

Written work will be graded for conciseness and correctness. Use formal arguments. Be brief and to the point and write clearly. Material covered in class and appearing in the relevant notes and chapters of the designated textbook can be used without proof. DO NOT USE PENCILS to write down your solutions; if you do use a pencil do not complain about grading after an exam. Read Handout 2 re grading of the MP.

MP-Grading

You are responsible for archiving and making sure dearchiving, compilation, and execution takes place properly in any one of the test platforms (see Handout 2). It is thus imperative to test your archive (and code) in those platforms. If dearchiving, compilation or execution fails, you will not be contacted. Do not expect partial credit without a DETAILED BUG REPORT. See Handout 2 for details.

Grades

Check the marks in written work and report errors promptly. Resolve any issues WITHIN 2 CALENDAR WEEKS and definitely before the first Reading Day from the day an exam is returned in class; for MP or Exam4, within 5 calendar days from the day grades were emailed or posted on Banner respectively. Talk to the grader first and then to the instructor (if different). The final grade is decided based on a 0 to 1000 point scale. A 25\% or less in the final exam will get you an F. If you get more than 25\% in the final and collect at least 500 points you should expect a C or better. 850 points or more are usually needed for an A but this threshold can vary (be lower). If you score less than 500 points the only way to avoid a D or F is to do well in the cumulative final (say more or half of the points) or have excess programming points. (All these assuming no violation of the Collaboration policy.)

Incomplete

A grade of I(incomplete) is given in rare cases where work cannot be completed during the semester due to documented long-term illness or absence (e.g. unexpected national guard duty). A student needs to be in good standing (i.e. passing the course before the absence) and receives a provisional I if there is no time to makeup for the documented lost time; a letter (or email) with a timeline of what is needed to be done will be sent to the student. Note that for most cases an I would be resolved within few days, not months and not the following semester! Not showing up in the final will probably get you an F rather than an I.

Collaboration

Collaboration of any kind is PROHIBITED in the in-class exams and the MP. For MP, a student must turn in code that has fully been written by him/her and no-one else. Any submitted code (even few lines) obtained through the Internet or otherwise, or is product of someone else's work or is common with another student submission, in the same or other section/course, risks severe punishment, as outlined by the University; all parties of such interaction receive automatically 0 and grade is lowered by one or two levels. The work you submit must be the result of your own mental effort and you must safeguard it from other parties; if you can't protect your home computer, use a Lab (AFS) machine.

Mobile Devices

Switch off (not just silence) mobile devices before class. IF A STUDENT GETS CAUGHT HAVING A PHONE/MOBILE DEVICE (on or off) ON HIM/HER DURING an exam, it is graded 0. DEVICES MUST BE OFF, AND in A BAG/BACKPACK, NOT ON YOU.
