6.042 Spring '15 Class OverviewContents
IntroductionThis subject offers an introduction to Discrete Mathematics oriented toward Computer Science and Engineering. This Spring there are two class sessions MWF in 32044 (EECS Tutorial Lounge):
The subject coverage divides into three parts:
The prerequisite is 18.01 (first term calculus), in particular, some familiarity with sequences and series, limits, and differentiation and integration of functions of one variable. The goals of the class are summarized in a statement of Class Objectives and Educational Outcomes. A detailed schedule of topic coverage appears in the Class Calendar. Considerations for Taking the Subject This TermThere are two main considerations for students in deciding to take 6.042J/18.062J this term ––or at all.
Weekly Schedule
Class WebsiteThe class has a comprehensive Stellar web site where notes, problem sets, solutions, etc., will be posted. Announcement and staff contact information are also available on this website. It is always worth checking the website for corrections and announcements before starting problem sets.Problem SetsProblem sets count for 15% of the final grade. Making a reasonable effort on the problem sets is, for most students, crucial for mastering the course material. Problem sets are designed to be completed in at most 3 hours; the time is monitored through student reports. Online Feedback ProblemsOnline problems to be completed before most class meetings are posted on the 6.042r website. These consist of straightforward questions that provide useful feedback about the assigned material. (Some students prefer to try the online problems before reading the text or watching videos as an advance guide to going over the material; that's fine.) Watching designated videos, or at least looking at the lectureslide handouts, is generally helpful but optional.Like team problemsolving in class, online problems are graded solely on participation: students receive full credit as long as they try the problem, even if their answer is wrong. Online feedback problems count for 5% of the final grade. CollaborationYou are encouraged to collaborate on problem sets as you do on teams in class. However, you must cite all your collaborators and any sources beyond this term's class materials that you consulted while working on a problem––for example, an "expert" consultant other than 6.042 staff, or another text––must be given a proper scholarly citation, which you should include with the collaboration statement accompanying your submission. Class materials (excluding solutions) from Spring '14 are available on the Spring '14 Stellar web site. Materials including some solutions are available on MIT OCW for Fall '10, Spring '10.A problem from prior terms may occasionally be assigned again without change. If you find a published solution, you should cite it, and you may not simply copy it. Instead, submit a critique of the published solution, an improved solution, or a suggestion for an improved or variant version––basically any commentary that shows engagement with the material comparable to that required to solve the problem on its own. We discourage, but do not forbid, use of materials from terms prior to Spring '14. We repeat, however, that use of material from a previous term requires a proper scholarly citation. As long as you provide an accurate citation and collaboration statement, a questionable submission will rarely be sanctioned––instead, we'll explain why we judge the submission unsatisfactory (and maybe deny credit for a specific, clearly copied solution). But omission of such a citation will be taken as a priori evidence of cheating, with undesirable consequences for everyone. Midterm ExamsThree 80 minute midterm exams will be given in class on on Wednesday, February 25, March 18, and April 15. The midterm exams each count for a total of 10% of the final grade.Midterm questions will typically be variations of prior problems from class and psets, and the best way to prepare is to review on the published solutions to these problems. The first exam covers all previous weeks' material; subsequent exams focus on the material after the previous exam. The material on the Monday before midterms 2 & 3 will not be covered, but because of lost days to snow, induction will be covered by midterm 1. A single twosided crib sheet is allowed for each midterm. Final ExamThere will be a three hour final exam during exam period on Thursday, May 21, 9AM in 34101. This exam is worth 25% of the final class grade.The final exam will cover the entire subject with somewhat greater emphasis on material from after Midterm 3. Most exam questions will be variants of problems assigned during the term (pset, class, midterm, and online). It may include a few questions which combine topics that were originally covered separately. A pair of twosided crib sheets (total: 4 sides) are allowed for the final. GradesGrades for the class are based on the following weighting:
The lowest problem set score and lowest three (3) class session scores will not count in grade calculation. This effectively gives you a problem set and three class sessions you can miss without excuse or penalty. You should notify the staff in advance of an absence if possible, and briefly indicate the reason. Think of the three absences as "personal" days which you may use for sick leave, professional conflicts like job interviews, or sleeping in. Waivers and makeups for missed psets or absences will be considered only after the one pset or three allowed absence waivers are used up. The class is not graded on a curve. In fact, MIT policy (Rules and Regulations of the Faculty, section 2.62) does not allow grading according to a fixed grade distribution. Instead, students are assessed individually. In particular, students who remain in class after Drop Date are not in jeopardy of seeing their grades change due to the change in class composition. While there is no curve, it is expected that 6.042J/18.062J will be "(A/B+)centered" with more than 10% unsatisfactory grades (D or F) unlikely.Questions, Suggestions, and Complaints to the StaffMessages for the staff can be posted (publicly or privately) on the class Piazza forum or by email to Email addresses for individual staff members are available on the Stellar site.
