Course Description

An introduction to classical algorithms with a focus on implementation and applications. Covers both analysis and implementation of algorithms. Algorithms include searching, sorting, and shortest path. Data Structures and their analysis is also covered. Data Structures include trees and graphs.

Course Objective and Goals

1. Learn to analyze the running time of iterative and recursive algorithms.
2. Learn to analyze the running time of data structures.
3. Gain familiarity with basic data structures and algorithms related to them, such as trees and graphs.
4. Learn various applications of algorithms and data structures.
5. Learn to choose the correct data structure to efficiently solve problems.
6. Learn the basic theoretical foundations of computation.

Topics

1. Algorithm Fundamentals
2. Recursion
3. Searching and Sorting
4. Fundamentals of Simple Data Structures( lists, trees, graphs)
5. Intro to algorithm analysis and order of growth
6. Intro to algorithms in distributed systems.

Audience and Purpose within Plan of Study

• If Class in Run Online: lectures will be pre-recorded and posted in BBLearn. Class time will be used for additional office hours.

Homework Assignments

• Homework will contain both written and programming questions.
• Homework will be submitted using learn.drexel.edu
• Homework Assignments are due on Thursdays at 11:59PM
• Homework Assignments are to be completed individually.

Blogs

• Each week with have a reading and blog reflection.
• Blogs are due on Friday at 11:59PM.
• You must comment on two other student's blogs by the Sunday at 11:59PM

Research Papers

• Students will complete two research papers.
• Midterm RP: Due Friday 11:59PM of week 6.
• Final RP: Due Friday 11:59PM of Finals Week.
• Research Papers are to be completed individually.

Discord Channel

• This term, we will be using a Discord channel instead of a discussion board.
• Your account will be created by Drexel CCI during the first week of classes. Instructions will be provided by Drexel CCI.
• If you have any problems with your Discord account please email ihelp@drexel.edu. The Professor and Teaching Assistants cannot create/modify discord.

Late Submissions

• Each student has two "late passes".
• A student may exchange one of their late passes for an one day extension on any assignment.
• Contact the TA/Professor to request one of your late passes be used.
• You may use both late passes of the same assignment to get a 2 day extension.
• Without late passes, -10% per day for up to 4 days.

Special Circumstances

• If you have a documented reason why you cannot submit an assignment by the deadline, a special exception may be made. The Professor may also wave the late submission penalty for documented special exceptions.

Course Policies

The CCI Academic Honesty policy is in effect for this course. Please see the policy at http://drexel.edu/cci/resources/current-students/undergraduate/policies/cs-academic-integrity/.

Academic Honesty Violations will be reported to the University. Punishment will be determined by the severity of the incident. Punishments include, but are not limited to,

• Failing grade for class
• Deduction of one letter grade
• Zero on Assignment/Exam Violation took place on

Grading and Policies

• Homeworks 50%
• Blog Posts 10%
• Blog Comments 4%

Appropriate Use of Course Materials

It is important to recognize that some or all of the course materials provided to you are the intellectual property of Drexel University, the course instructor, or others. Use of this intellectual property is governed by Drexel University policies, including the IT-1 policy found at: https://drexel.edu/it/about/policies/policies/01-Acceptable-Use/
Briefly, this policy states that all course materials including recordings provided by the given prior written approval by the University. Doing so may be considered a breach of this policy and will be investigated and addressed as possible academic dishonesty, among other potential violations. Improper use of such materials may also constitute a violation of the University's Code of Conduct found at: https://drexel.edu/cpo/policies/cpo-1/ and will be investigated as such.

Recording of Class Activities:

In general, students and others should not record course interactions and course activities in lecture, lab, studio or recitation.
Students who have an approved accommodation from the Office of Disability Resources to record online lectures and discussions for note taking purposes should inform their course instructor(s) of their approved accommodation in advance. The recording of lectures and discussions may only be carried out by the students enrolled in the class who have an approved accommodation from Disability Resources with their instructors' prior knowledge and consent. Students with approved accommodations may be asked to turn off their recorder if confidential or personal information is presented.
If a student has any comments, concerns, or questions about provided class materials and/ or recording, talk to your course instructor first. If this does not resolve the issue, you can also reach out to the Department Head, and use the process described for a grade appeal to move your concern forward. The process described for grade appeals can be found at: https://drexel.edu/provost/policies/grade-appeals/
