The Sonoma State University Catalog provides the following description for CS 415, Algorithm Analysis:

Formal Description From the Sonoma State University Catalog:

Expanding this description somewhat, CS 415 examines the design, implementation, and efficiency of algorithms, extending the study begun in CS 115 and continued in CS 215, CS 242, and CS 315. The course has four main foci:

• Alternative strategies in the design of algorithms,
• Relationships between algorithms and data structures:
  • Some algorithms (e.g., numerical methods) solve problems with little need for extensive data structures,
  • Some algorithms evolve to support abstract data types (e.g., graphs, trees, hash-based structures) and their underlying data structures (e.g., arrays and linked lists), and
  • Some algorithms require careful record keeping, requiring the design and use of their own internal data structures (e.g., construction of optimal binary search trees).
• Careful analysis of the efficiency of these algorithms, regarding both run-time performance and resource use.
• Techniques for establishing algorithm correctness.

Course Meeting Information:

• Class Meetings: Tuesdays and Thursdays, 1:00-2:50 pm
• Classroom: Salazar Hall 1035

Expanding on the course description, CS 415 has these high-level goals:

• to gain proficiency in the use of a variety of strategies for algorithm development
• to understand and apply fundamental algorithms to a range of problems
• to learn representative algorithms that are largely independent of data structures, algorithms that support abstract data types and data structures, and algorithms that utilize their own data structures for record keeping
• to learn techniques for analyzing algorithms, such as instruction counts, recurrence relations, probability theory
• to understand and apply the concept of loop invariants as part of the development of algorithms and programs
• to understand and apply methods for showing the correctness of algorithms to solve sample problems

The objectives of CS 415 include these capabilities:

• Students should be able to identify and explain several strategies for algorithm development and provide at least one example illustrating each strategy.
• Students should be able to explain, implement, and analyze fundamental algorithms from several application domains, such as trees, graphs, and hash-based structure.
• When several different algorithms are available for a task, students should be able to apply careful analysis to determine conditions under which one algorithm is better or worse than another.
• Since algorithms are normally designed to help solve problems, students should be able to provide formal arguments establishing that proposed algorithms meet their respective specifications.

This course incorporates a variety of activities, From past experience, the time required for these activities will likely vary substantially from student to student and from one part of the course to another. For example, a student may need to devote considerable time and effort when starting a new or different topic, but the workload may drop noticeably when that material is mastered.

Such variation in student experiences complicates any estimation of the time individual students may need to devote to homework for this course. However, from past experience, students working steadily on the course likely should expect to allocate 10-15 hours per week to homework. Some students may require additional time for some weeks; some students may complete work in less time for some weeks. Conversations with computer science faculty and others suggest this time allocation is consistent with expectations for many courses at Grinnell College and Sonoma State University.

While the schedule for this course is expected to evolve, a detailed Tentative Class Schedule is posted with readings, labs and worksheets, in-class quizzes and tests, etc. This schedule will be updated as the course evolves.

For variety, this course will utilize a variety of activities, including.

• opening discussion with student questions
• lectures by the instructor with discussion
• polling/clicker questions (as seems appropriate)
• labs and worksheets, including programming and experimentation
• quizzes (40-50 minutes each)
• tests (90-110 minutes)
• a final exam during exam week.

Course Work will involve a combination of several activities.

• Weekly Assignments (identified, with links, on the Tentative Class Schedule) are combination of labs (e.g., programming-oriented exercises) and worksheets (e.g., problem-oriented tasks mostly done on paper). Each of these assignments are designed to provide practice on topics covered in class and the textbook and to extend work with selected topics. Unless otherwise specified on the Tentative Class Schedule, labs/worksheets cover material since the previous assignment and are due the second-class day after appearing on the schedule. Thus, a lab/worksheet appearing on the schedule on a Thursday will highlight material covered on that Thursday and the preceding Tuesday, and will be due the following Thursday.

• In-class Quizzes: A 40-50 minute quiz will be scheduled on Thursday about every other week, except when Tests are scheduled. Altogether about 6 quizzes are scheduled during the semester; in grading, the lowest quiz score will be dropped. These quizzes will focus on basic topics covered recently, but prior to the previous class session.

  • One principle in this course is that students should be able to ask questions about a topic before the material appears on a quiz or test. Following that principle, material introduced the class before a quiz or test will not appear on that exercise. However, all material covered before that class could appear.
  • Since material in this course is cumulative, some recent work may require use of earlier material, so that earlier work could be useful during a quiz or test.

• Tests: Two in-class tests are scheduled for Thursday, September 29, and Thursday, November 4. These tests will focus on the previous 4-6 weeks of the semester, although some earlier material may be covered.

• Exam: A final exam will be given during Exam week, on Tuesday, December 13, at 1:00 pm, following the University's Final Examination schedule. This exam will be cumulative—including material from throughout the semester.

Deadlines

Worksheets and labs are due at the start of class, two class days after they appear on the Tentative Class Schedule. A penalty of 30% per class meeting will be assessed for any assignment turned in late, even work submitted at the end of a class.

Emergencies and Illness

Although dates for assignments, quizzes, tests, and the final exam are firm, I understand that circumstances arise when you are not able to attend class.

• When circumstances are known ahead of time (e.g., academic activities, athletic events), I expect you to make arrangements with me before the activity occurs. Normally, we will identify an alternative date for the due date, quiz, or test.

• When circumstances cannot be reasonably anticipated (e.g., illness, family emergencies), I expect you to notify me as soon as is reasonably possible. (Email is fine.) In the case of medical problems, I expect a written note from a medical professional or counselor that indicates that your health interfered with the course activity. (I do not need to know any details of the medical problem, but I do need to know that you sought help and that the medical professional believed meeting the deadline would likely interfere with your health.)

Absolute Deadline: All homework must be turned in by Thursday, December 8, at 4:00 pm;
assignments received after that time will not be counted in the grading of the course.

Written assignments, including Worksheets and Labs: All work is to be done individually. Outside sources (including consultation of in-class slides or the course textbook) may be used, provided students must follow university-wide rules for quotation and citation. In particular, every written source (including the textbook) must be identified, with sufficient information that the source could be easily found. For example, specific URLs are required for online sources (a general reference, such as wikipedia.org, is not sufficient, as Wikipedia contains thousands of pages). Further, references to books or articles must include page numbers. Also, if an answer uses material from past courses or previous work with individuals, the details of that material must be given explicitly.

Quizzes, tests, and the final exam: All quizzes, tests, and the final exam are closed book and closed notes, and collaboration is not allowed. Students may ask questions of the instructor, but communication with any other person is not allowed.

Other Graded Work: Should other work be assigned during this class, rules regarding collaboration and citation will be included as part of the activity.

Procedures: Throughout the course, any hint of academic dishonesty will be investigated and handled following the SSU Policies on Cheating and Plagiarism.

Cell phones, text-messaging devices, and other social-networking connections may not be used in this class. If you bring such equipment to the classroom, it must be turned off before the class starts and stay off throughout the class period. Use of such equipment is distracting to those nearby and will not be tolerated.

Assignments

As an upper-level course, answers to assignments must demonstrate care in organization and presentation.

• All assignments must be submitted in paper:
• All work must utilize a dark font (e.g., black, dark blue, dark green, dark red) on a light background (e.g., white, cream, light grey, light tan).
• Solutions must be organized in problem order, and each solution must indicate the problem number being addressed. However, there is no need to include the text of the questions.
• All programs submitted for credit must follow the CS 415 C/C++ Style Guide, which will be discussed in class. For example, since every programming task should yield readable and carefully tested code, the grading of all programs for this course will begin with the following algorithm (expressed in C format):

     if ((no_comments)
          || (missing pre- or post-conditions)
          || (formatting_does_not_show_structure)
          || (long_procedures_not_divided_into_sections_with_clarifying_comments)
          || (no_evidence_of_compilation)
          || (no_test_plan,__no_listing_of_circumstances__OR__no_listing_of_test_cases)
          || (no_test_runs)
          || (no_commentary_on_correctness)
          || (no_certification_regarding_sources_and_help)
          || (use of Bubble Sort or non-approved sorting algorithm)
     return (no_grade);
     

• Solutions to computational problems must include the work involved—presented in a logical order. Scattering computations in multiple sections of the page, or giving only the answer is not adequate and often will lose points.
• When a problem asks for explanations or logical arguments, answers must utilize proper English grammar and follow a logical presentation. For example, statements must be in full English sentences and follow standard rules of English construction. Points may be subtracted for sloppy or poorly constructed English prose or egregious errors in spelling. Typically, occasional mistakes (1-2 per page) likely will not be penalized, although systematic spelling errors may be subject to a penalty. Beyond occasional difficulties, point penalties will depend on the frequency and severity of the errors. See the instructor, if you have questions about writing—I would be delighted to help you with your technical writing skills.

Semester Grades

This instructor's grading philosophy dictates that the final grade should ultimately be based upon each student's demonstration of her or his understanding of the material, not on the performance of the class as a whole nor on a strict percentile basis.

The following scheme is proposed as a base for how the various assignments and tests will be counted in the final grade.

Fires and/or Power Outages

Sonoma County has seen an increase in fire activity and public safety power outages that have had an impact on campus operations intermittently since 2017. In the event that we experience a similar disruption to our course this semester, I will communicate with class via email within 24 hours of the disruption around potential changes to assignments, due dates, or readings. If the disruption continues for more than one week of our regular class meetings, I will subsequently follow up on a weekly basis. Please sign up to receive university emergency alerts by texting SSUALERTS to 67283.

Covid-19

In accordance with state and county guidelines, masking in SSU instructional spaces is strongly recommended in the Fall 2022 semester. Any changes regarding campus COVID-19 requirements or policies will be communicated to the campus community via email.

Religious Observance

The observance of religious holidays (activities observed by a religious group of which a student is a member) and cultural practices are an important reflection of diversity. As your instructor, I am committed to providing equivalent educational opportunities to students of all belief systems. At the beginning of the semester, you should review the course requirements to identify foreseeable conflicts with assignments, exams, or other required attendance. If at all possible, please contact me (your course coordinator/s) within the first two weeks of the first class meeting to allow time for us to discuss and make fair and reasonable adjustments to the schedule and/or tasks.

Flexibility versus Accommodations

I have designed the course to provide some flexibility for students who experience hardships related to COVID-19 and other illnesses, mental health challenges and family concerns. These include reasonable extensions on assignments, and opportunities to make-up exams. It is important to note that any flexibility that I provide is something that I would offer any student without compromising the learning outcomes or modalities of the course. For instance, I cannot change the course modality to online for a student, nor can I allow a student to use notes in a traditionally closed notes exam. The most important thing that you can do is communicate with me. I can work with you to determine what options there are for you to succeed.

This flexibility should not be confused with the term "accommodations" which is reserved for students referred to me by Disability Services for Students (DSS).

DSS

If you are a student with a disability, and think you may need academic accommodations, please contact Disability Services for Students (DSS), located in Schulz 1014A, Voice: (707) 664-2677, TTY/TDD: (707) 664-2958, as early as possible in order to avoid a delay in receiving accommodation services. Use of DSS services, including testing accommodations, requires prior authorization by DSS in compliance with university policies and procedures. See SSU's policy on Disability Access for Students.
