Course Objectives

From the course catalog: "This course continues previous work in the design and analys of algorithms. Data structures considered may include, for example, binary trees, AVL trees, B-trees, hash tables, and multi-dimensional trees. Algorithms for searching, inserting into, and deleting from these structures will be discussed. A variety of sorting algorithms (possibly including radix sort, heapsort, mergesort and quicksort) will be studied. Algorithms for other problems such as k-selection, minimum cost spanning trees, connectivity, and shortest paths will be analyzed. NP-complete problems will be introduced."

**Course Goals**

- To learn about advanced algorithms and data structures.
- To develop the ability to analyze an algorithm for time and space complexity.
- To utilize and further develop proof techniques introduced in Discrete Structures to formalize this analysis.
- To enhance programming skills by implementing, testing, and utilizing algorithms.
- To learn to use LaTeX to typeset a technical document.

Prerequisites

Texts

The required text for the course is * Introduction to the Design and Analysis of Algorithms, Second Edition*
(Addison Wesley, 2007, ISBN 0-321-35828-7) by Anany Levitin. This is available from
the Siena Bookstore (and elsewhere). If you buy elsewhere,
be sure to get the correct edition.

Lectures

Everyone is expected to attend class and participate in discussions. There is no formal attendance policy, but a lack of regular attendance is certain to result in lower grades on assignments and exams. Do not expect sympathy if you are stuggling but are rarely seen in class and during office hours. Supplemental readings are listed on the lecture and reading schedule. Of course you are encouraged to do the reading, and you will benefit from doing so, but all important topics will be covered in class.

Be prompt, prepared, and ready to focus on the day's topics. This
should go without saying, but this means your phones and other devices
not being used *exclusively* to follow along with class materials
and/or to take notes must be powered off. You may bring food or drink
to class, as long as you are not a distraction to your classmates or
instructor.

Most lectures will include a small assignment due at the start of the next class. Some lectures will begin with a short pop quiz. No late submissions of these "lecture assignments" or quizzes will be accepted, as they will often be discussed in class on the due date or immediately following the quiz. Some assignments will be graded for correctness, while others will be graded based on whether an honest effort was made.

The lecture and reading schedule has a link to a web page for each lecture highlighting the day's topics, listing class examples, and the lecture assignment due the next class. The notes used to guide in-class presentations are also available as PDF files linked from the lecture and reading schedule.

Problem Sets

A series of approximately 8 problem sets will be assigned. The number of points available will vary with the complexity of the assignment.

Some problems sets will require programming. For programming
assignments, you may develop your programs anywhere (computers in the
lab, your own PC, *etc.*) but grading will be done using
the Siena Computer Science Linux systems unless otherwise specified. It is your
responsibility to ensure that your program works on the grading
platform. Programming assignments will be graded on design,
documentation, style, correctness, and efficiency.

Most problem sets will require you to analyze algorithms and data structures, often including formal proofs. Your solutions should be written clearly and concisely. You should rewrite your proofs once you have worked them through once to ensure they are clear and flow well. You will learn to use the LaTeX mathematical typesetting system in early assignments and make extensive use of it throughout the semester (and, hopefully, for much of your career as computer scientists).

Unless otherwise specified, late problem sets may be turned in with a
penalty computed as *1.08 ^{h}%*, where

Exams

There will be two exams during the semester, plus one during finals period. The two regular exams will be take-home exams. The final exam will be scheduled by the Registrar during the exam period in May.

Grading

Grades for individual assignments and exams
are not scaled. Any scaling deemed appropriate will take place at
the end of the semester by adjusting the above thresholds. The
following thresholds *may* be adjusted downward (thereby raising
grades) but will never be adjusted upward.

| Scale: | ||||||

Lecture Assignments/Quizzes | 10% | A >= 93% | A- >= 90% | ||||

Problem Sets | 40% | B+ >= 87% | B >= 83% | B- >= 80% | |||

Exam 1 | 15% | C+ >= 77% | C >= 73% | C- >= 70% | |||

Exam 2 | 15% | D+ >= 67% | D >= 63% | D- >= 60% | |||

Final Exam | 20% | F < 60% | |||||

Academic Integrity

You are encouraged to discuss the concepts related to course assignments and exams with your classmates. This is an essential part of a healthy academic environment. However, work submitted for grading must be your own (or the combined work of group members, for group assignments). Any unauthorized copying or collaboration is considered a breach of academic integrity and will not be tolerated. Academic dishonesty cases are unpleasant and uncomfortable for everyone involved. You are responsible for reading and understanding the College Catalog Statement on Academic Integrity and the Computer Science Department's Academic Integrity statement. The minimum penalties for a first violation will include failure (0 grade) for the assignment or exam in question and the filing of a Academic Integrity Violation Accusation Form. A second violation will result in failure of the course and a formal letter describing your misconduct will be sent to the head of the Computer Science Department and the Office of Academic Affairs.

If there is any doubt about the degree of collaboration allowed or the
permitted sources for a particular assignment, please ask for
clarification **before** collaborating or consulting the source.
Any such collaborations or sources must be cited properly.
