Notes:

Source:

This course introduces basic elements of the design and analysis of computer algorithms. Topics include asymptotic notations and analysis, divide and conquer strategy, greedy methods, dynamic programming, basic graph algorithms, NP-completeness, and approximation algorithms. For each topic, beside in-depth coverage, one or more representative problems and their algorithms shall be discussed.

Analyze the asymptotic performance of algorithms, Demonstrate a familiarity with major algorithm design techniques, Apply important algorithmic design paradigms and methods of analysis, Solve simple to moderately difficult algorithmic problems arising in applications, Able to demonstrate the hardness of simple NP-complete problems

This course can be learnt in effective way only if focus is given on practical aspects of algorithms and techniques discussed in class. Therefore student should be able to implement the algorithms and analyze their behavior.

This syllabus follows the official B.Sc. CSIT curriculum of Tribhuvan University. In case of any doubt or revision, the university's published syllabus shall be considered authoritative.
