Course description

The course introduces the basics of computational complexity analysis and various algorithm design paradigms. It covers the major algorithms and data structures for searching, sorting, parsing, and memory management. Other topics include theoretical models of computation, concepts of algorithm complexity, computability, and NP-completeness.

Prerequisites: CSE31; proficient level of programming skills in C/C++/Java and elementary data structures; basic math and probability knowledge.

Homeworks

Homework (to do on your own, graded):

Homework #1 (covering chapters 1-4 from the book): due Feb. 19 at the beginning of the lecture.
Homework #2 (covering chapters 6-12 from the book): due Mar. 12 at the beginning of the lecture.
Homework #3 (covering chapters 15-16 from the book): due Apr. 21 at the beginning of the lecture.
Homework #4 (covering chapters 22-24 from the book): due May 6 during your lab session.

Project

Optional project (to do on your own, for extra credit), in groups of 4 students, due May 8 11:59pm PST by email to the TA. You have a choice among the following two different projects:

Project 1: experimental run times of sorting algorithms.
Project 2: experimental run times of hash tables with open addressing.

Course grading

Midterm exam (30%): in-class, closed-book, consisting of problems and conceptual questions. It will cover ch. 1-12 (parts I-III) inclusive.
Final exam (30%): as the midterm. It will cover the entire course, but mostly focusing on the part after the midterm.
Lab assignments (20%): these consist of programming selected algorithms in C and C++, and will be graded within the lab session.
Homeworks (20%): exercises and problems similar to those in the textbook to be submitted approximately biweekly.
Optional project for up to 10% extra credit.

While I encourage you to discuss your work with other students, the homeworks, lab assignments, project and exams must be the result of your own work without collaboration. See the Academic Dishonesty Statement and the UC Merced Academic Honesty Policy.

Grade curves: midterm, final.
