Approximation Algorithms
The lecture notes on Approximation Algorithms by Shuchi Chawla focus on techniques of designing algorithms that produce near-optimal solutions to complex optimization problems for which finding an exact solution is computationally infeasible. These lecture notes cover general underlying techniques of approximation algorithms, comprising basic building blocks and the foundation needed to deal with problems which are difficult to solve exactly due to computational complexity. These notes by Chawla provide an outline of various methods for approaching different optimization problems and ways of solving them when exact algorithms are not practical. Further, this resource is likely to be extremely helpful with respect to devising and applying approximation algorithms returning good solutions within a reasonable amount of time; hence, this is a must for scholars and practitioners faced with hard optimization problems.

Lecture Notes on Design and Analysis of Algorithms
These ecture notes give a comprehensive introduction to the basic techniques in the design and analysis of algorithms. It covers major methodologies, including greedy methods, which build up solutions piece by piece; dynamic programming (DP), which breaks down problems into simpler subproblems, solves them, and memorizes their solutions; and backtracking, which incrementally generates candidates for solutions and discards those that cannot satisfy criteria. It also discusses the method of Branch and Bound, where all branches on a solution space are systematically explored until the best possible solution is obtained. These methods are crucial in the design of nice algorithms with a view to efficiency, and they form the basis of complex computational problems that require solutions.

Advanced Algorithms by BMS College of Engineering
This PDF deals with some advanced topics in the design of algorithms, focusing on Dynamic Programming. The application domains of DP are discussed and cover classic problems, including Matrix Chain Multiplication, that is, finding an optimal order to multiply many matrices, and Rod Cutting, which is just a typical 4-inch rod problem. Its notes include insights into the steps of DP, its recursive tree structures, and problem-solving through the bottom-up approach. The wide de-balcony of these topics helps the reader understand how DP can be applied to a variety of optimization problems and demonstrates both theoretical and practical aspects of algorithm design.

Distributed Algorithms Lecture Notes
Prof. Nancy Lynch's Distributed Algorithms Lecture Notes has a great amount of detail concerning algorithms designed for distributed systems within which important aspects are that of multiple processors executing without centralized control. This paper investigates the model assumptions and organization strategies tasked with the two basic timing models. It also looks at synchronous, asynchronous, and partially synchronous models and synchronous networks. They discuss various models, thus enable the researchers to understand what one is actually up against and what strategies one can use in order to design algorithms working effectively in distributed environments. Hence, Lynch's notes are a must-have for any researcher who aims to know how to manage communication and coordination in distributed systems. Therefore, ideal for use by students and professionals dealing with distributed computing and networked systems.
