Prof. Mukhopadhyay brings a wealth of academic and research experience to the table. His educational journey includes a B.Sc. (Honours in Mathematics) from the University of Calcutta, followed by an M.Stat and an M.Tech from the Indian Statistical Institute. He earned his Ph.D. in Computer Science, specializing in Cryptology, from the same institute.

His global research experience includes positions at the National University of Singapore (NUS), Inria Rocquencourt in France, Nanyang Technological University (NTU) in Singapore, and Dublin City University (DCU) in Ireland. This diverse background ensures that the course content is not only theoretically sound but also informed by international research standards and practical applications.

Course Overview: What Will You Learn?

This course is an introduction to the mathematical modeling of computational problems. It goes beyond mere coding to answer the fundamental questions of why and how algorithms work, and how to evaluate their efficiency. The primary objectives are:

• To cover common algorithms, algorithmic paradigms (like Divide and Conquer, Dynamic Programming), and essential data structures.
• To clarify the intrinsic relationship between algorithms and programming.
• To introduce key performance measures and analysis techniques, primarily using asymptotic notation.

Intended Audience: This is a core course suitable for B.Tech, B.E., M.Tech, and M.Sc. students in Computer Science and Engineering.
Industry Support: The skills taught are directly relevant and highly sought after by IT companies worldwide.

Detailed 4-Week Course Layout

The curriculum is meticulously planned to build your understanding from the ground up over four intensive weeks.

Week 1: Foundations of Algorithmic Analysis

• Insertion Sort: Start with a simple, intuitive sorting algorithm to understand basic operation counting.
• Asymptotic Notation (Big-O, Theta, Omega): The crucial language for describing algorithm efficiency.
• Merge Sort & QuickSort: Dive into efficient, recursive sorting algorithms.
• Divide and Conquer Paradigm: Learn this powerful problem-solving strategy exemplified by Merge Sort.

Week 2: Advanced Sorting and Selection

• Heap Sort: Understand sorting using the elegant heap data structure.
• Linear-time Sorting: Explore algorithms like Counting Sort and Radix Sort that break the O(n log n) barrier under specific conditions.
• Order Statistics: Learn algorithms to efficiently find the i-th smallest element in a set (like the median).

Week 3: Data Structures and Advanced Design Techniques

• Hashing: Master one of the most important concepts for achieving constant-time lookups.
• BST Sort & Binary Search Trees: Explore dynamic data structures for maintaining sorted data.
• Augmenting Data Structures: Learn how to customize standard structures to support new operations.
• Dynamic Programming: Unlock the technique of solving complex problems by breaking them down into overlapping subproblems and storing their results.

Week 4: Graph Algorithms

• Graph Representations & Traversals: Breadth-First Search (BFS) and Depth-First Search (DFS).
• Minimum Spanning Trees: Prim's algorithm for finding the least-weight tree connecting all vertices.
• Shortest Paths: Foundational algorithms for finding the shortest path in a weighted graph (like Dijkstra's).

Primary Reference Textbook

The course closely follows the definitive text in the field:
"Introduction to Algorithms" (3rd Edition) by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein. Often referred to as "CLRS," this book is the bible of algorithm studies and will be an invaluable companion throughout the course and your career.

Why Should You Enroll?

Whether you are a student preparing for campus placements, a professional aiming to strengthen your core skills, or an enthusiast wanting to understand the logic behind efficient software, this course is for you. Prof. Sourav Mukhopadhyay's structured approach, combined with the rigorous IIT standard, ensures you gain a deep, practical, and analytical understanding of the algorithms that form the backbone of modern computing.
