An Introduction to Algorithms and Analysis

An Introduction to Algorithms and Analysis. Instructor: Prof. Sourav Mukhopadhyay, Department of Mathematics, IIT Kharagpur. This course provides an introduction to mathematical modeling of computational problems. It covers the common algorithms, algorithmic paradigms, and data structures used to solve these problems. The course emphasizes the relationship between algorithms and programming, and introduces basic performance measures and analysis techniques for these problems. (from nptel.ac.in)
