Course description |
| The design and analysis of algorithms is the core subject matter of Computer Science. Given a problem, we want to (a) find an algorithm to solve the problem, (b) prove that the algorithm solves the problem correctly, and (c) prove that we cannot solve the problem any faster. Designing an algorithm for a computational problem involves knowledge of the problem domain, a thorough knowledge of the data structures that are available and suitable and no small measure of creativity. This course concentrates on the above problems, studying useful algorithmic design techniques, and methods for analyzing algorithms. |
Prerequisites |
| CS 365. Good knowledge of data structures (such as linked lists and trees) and a good mathematical background are required. |
Syllabus |
| Following are the topics that will be discussed, listed in the approximate order in which they will be covered. |
|
Class schedule |
| The topics presented and the lecture notes for each class will gradually be posted below as we cover them in the class. The assignments and their due dates will also be posted in this table. Please check this web page regularly for updates.
For homework submission please include a typed cover sheet with your name, section number and homework number. It would be desired to type the rest of your homework, but handwriting will be accepted. You can find instructions about writing your homework with LaTeX on Richard's webpage. |

Assignments and grading |
|||||||||||||||||||||||||||
|
Homework assignments: There will be 10 homework assignments. The homeworks and their due dates will be posted on the course web page. Homeworks are due on their specified date at the beginning of the class. Some assignments will contain extra-credit problems and some may have a programming component. For each assignment the undergraduate students are required to solve the problems labeled U-required, while graduate students are required to solve all the problems. For the assignments that include extra-credit problems, the undergraduate students can earn extra-credit by solving either the extra-credit or the graduate level problems. Solutions to all the problems assigned will be provided. Please make sure that you have a CS department computer account - you will need it for the programming assignments. You can obtain a CS department account by filling out the account registration form at the CS department. Late policy: each late homework will incur a 10% penalty for each day of delay, but no homeworks may be submitted later than 3 days after the deadline. Academic integrity: Students are encouraged to study together, however each student must individually prepare his/her solutions. Cheating or plagiarism are not permitted and will be sanctioned according with the UNR policy on Academic Standards. You should carefully read the section on Academic Dishonesty found in the UNR Student Handbook (copies of this section are on-line). Your continued enrollment in this course implies that you have read it, and that you subscribe to the principles stated therein. Exams: there will be one mid-term and one final exam. Both exams will be closed books, closed notes. Permission to take exams on other dates than scheduled will not be given, except for extreme medical emergencies.
