Course Description


Welcome to an introductory course in Algorithms! This course is a hands on teaching of the fundamentals of Algorithms. The fundamentals of algorithms includes how to write an algorithm, analyze an algorithm, and compare the performance of algorithms. In this class, we use the 'C' programming language (for which an introduction will be given), as our tool for implementing algorithms and data structures. Our other tools are pencil & paper, a text editor, and git. The expectation is that you have not previously programmed in the C programming language, but have previously programmed in some other language.

Registrar Description: Introduces the basic principles and techniques for the design and implementation of efficient algorithms and data representations. Considers divide-and-conquer algorithms, graph traversal algorithms, linear programming, and optimization techniques. Covers the fundamental structures for representing data, such as hash tables, trees, and graphs.

Course Objectives


By the end of this course, you will be ready to:

  • Analyze and understand the time complexity of a given algorithm.
  • Have a grasp of the mathematics used to understand algorithms, including familiarity with logrithms, polynomials, recurrences, and the master theorem.
  • Explain design trade-offs given a set of algorithms and data structures regarding their time and space copmlexity.
  • Be comfortable writing, compiling, and running small (less than 1000 line) C programs.

Resources



There will be no required textbook for this course. However, these resources have been vetted, and I recommend for mastery (while taking this course, and reviewing later on in your career).

Academic Integrity and Non-Discrimination


Students and instructors are to follow the Northeastern policies on these important issues.

  • Northeastern Non-Discrimination Policy - This classroom is a safe space for the instructor and students to talk about ideas, share viewpoints, and learn.
  • Northeastern Academic Integrity Policy - You only cheat yourself if you are not honest. Most often cheating occurs when an individual falls behind or perhaps has other circumstances occurring in their life. Please consult the instructor before ever considering cheating.
    • If you are caught cheating I have to report the violation. My official policy is you receive a 0 in the course. Always remember, if you use any external sources, you must cite them.
  • Student Code of Conduct: Students and instructors will follow the following guide for how we conduct ourselves. This is to create a respectful environment where everyone can learn.

Make-Up Policy


Students participating in varsity athletics(this does not include club sports or intramurals) or other University sanctioned events may have the need for a make-up. Please contact me in advance of such events, so that appropriate accommodations can be made.

Occasionally, other life events and circumstances occur that were not planned. If this is the case, please e-mail me privately.

E-mailing me asking for extensions just because is unfortunately not fair to your classmates. The 10% penalty for each day late has to be enforced so I do not get taken advantage of.

Accessibility


Part of what makes Northeastern University unique, is our diverse cohort of students, faculty, and staff. In order to support this, Northeastern is committed to providing equal access and support to all qualified students through the provision of reasonable accommodations so that each student may fully participate in the University experience. If you have a disability that requires accommodations, please contact the Student Accessibility Services office at DRC@northeastern.edu or (617) 373-2675 to make an appointment with the Disability Resource Center representatives in 20 Dodge Hall to determine appropriate accommodations.

Lateness and Attendance Policy


Students who do well in this course tend to show up to the course consistently, participate, and engage with their peers. Come to class, come on time, and build good habits! In-Class activities that are not attended are a zero.

Assessment/Course Polices


Please find below the grading distribution that will be used for this course to compute a weighted average for your final grade. You will find the grade you earn in this course on blackboard.

  • In-Class Activity: 5%
  • In-Class Labs:     20%
  • Exam/Quiz:         20%
  • Assignments:       55%
    • (Each Assignment worth the same % of points)

  • The grade system follows the University Grading System.
    • A  = 95 – 100
    • A- = 91 – 94
    • B+ = 87 – 90
    • B  = 83 – 86
    • B- = 80 – 82
    • C+ = 77 – 79
    • C  = 73 – 76
    • D+ = 67 – 69
    • D  = 63 – 66
    • F  =  0 – 62
  • In the event of a snow day (i.e. we miss a lab or in-class activity) the weight of each assignment increases (There may also be shuffling of course material if we are interrupted).
  • The expectation is that the assignments are fair but difficult, so you should start early!
  • Late Submissions of Assignments receive 10% off per day submitted late (up to 3 days max, then 0% received).
    • Unfortunately, with 100+ students I cannot make individual exceptions fairly to your classmates who are likely making other personal sacrifices.
  • Assignments that do not compile/open receive no credit Simply put, programs that do not compile do not do anything.
  • There are no "re-grades" or points awarded one week after your grade is posted. "re-grades" may result in a higher, equal, or lower score.
    • There are no "re-grades" after the semester is over.
    • Do not ask multiple members of the course staff for "re-grades"
  • If you are currently wait listed, you must submit your homework on time. That is the gamble! If you do not have blackboard access, you will submit by e-mail or other course mechanism.
  • There are no extra credit assignments. I reserve the right to add points to assignments that do go above and beyond however.
  • I reserve the right to modify the grading scale in your favor if you show exemplary proficiency in any of the categories. I will never modify the scale to lower a students grade.
  • In class work cannot be made up at a later date unless otherwise arranged with the instructor well in advance.
    • Course work completed after the date cannot be graded, as solutions will have been discussed (this includes if taking this course for an Incomplete).
    • Once again, "in-class" work must be completed in-class unless there is a documented emergency or you have prearranged with the instructor a make-up well in advance.
  • No Facebook, no cell phones. Not only does it distract you, it distracts others! (Divide your tuition by lecture hours and perhaps you will be more motivated as well!)
  • Everyone needs to come see me in office hours (or by appointment) at least one time during the semester to introduce yourself. The purpose is so that you:
    • Know where my office is.
    • Get used to coming to office hours.
    • Let me know how I can help you achieve your goals.
