Solving large combinatorial optimization problems is a ubiquitous task across multiple disciplines. Developing efficientprocedures for solving these problems has been of great interest to both researchers and practitioners. Over the last half century, vast amounts of research have been devoted to studying various methods in tackling these problems. These methods can be divided into two categories, heuristic methods and exact algorithms. Heuristic methods can often lead to near optimal solutions in a relatively time efficient manner, but provide no guarantees on optimality. Exact algorithms guarantee optimality, but are often very time consuming.

An embedded system is a microprocessor-based computer hardware system with software. These systems are designed to perform different types of functions either as an independent system or as a part of a large system. An integrated circuit (IC) is an essential part of the embedded system that performs real-time computations and operations. The fundamental structure of any embedded system comprises five principal components which include sensors, A-D converter, processor & ASICs, D-A converter, and an actuator. Embedded systems are regulated by digital signal processors (DSP) or microcontrollers, field-programmable gate arrays (FPGA), GPU technology, etc. These processing systems are integrated with components specified to operate electric and/or mechanical interfacing. Embedded systems are widely used in consumer, industrial, automotive, and home appliances. They also have medical, telecommunication, commercial and aerospace applications. This book provides a comprehensive overview of embedded systems. With its detailed analyses and data, it will prove immensely beneficial to professionals and students interested in the design, technologies and applications of these systems.

Computer aided verification is a branch of computer science that focuses on creating tools and techniques to help programmers in verifying whether the software designed by them works correctly or not. These tools are being incorporated in the system design of firms. Computer aided verification strives to improve the quality of digital systems through the analysis of software designs using logical reasoning and software tools. The goal is to create a mathematical model of a system and then attempt to prove formal properties that either certifies the system's correctness or, at the very least aid in the detection of bugs. This book discusses the techniques and applications of computer aided verification. For all readers who are interested in computer aided verification, the studies included herein will serve as an excellent guide to develop a comprehensive understanding.

Computer aided verification process (CAV) comprises mathematically based strict approaches for the verification, specification and development of hardware and software systems. The goal of CAD is to make such systems more robust, correct and dependable. Mathematical theories, design phase and specification formalism are used to categorize verification methods. Methods for verification during the design phase comprise testing, specification and implementation. Markov chains, process algebras and timed automata are the processes done in specification formalism. Static analysis, model checking and theorem proving are part of the verification process in mathematical theories. SPIN, NuSMV, UPPAAL, CBMC, TLA+, dafny, and PRISM are some of the tools that can be utilized in CAV. This book elucidates the concepts and innovative models and prospective developments with respect to computer science and information technology. It will also provide interesting topics for research which interested readers can take up.
