Automated reasoning is a branch of artificial intelligence focused on the development of algorithms and systems that enable machines to perform logical reasoning tasks. It involves the development of algorithms and computational techniques that allow systems to perform tasks like theorem proving, problem-solving and logical inference. Key techniques include propositional logic, predicate logic and model checking. These methods help in verifying software, ensuring consistency in databases and supporting decision-making processes. Automated reasoning enhances the accuracy and efficiency of complex tasks by minimising human error. Techniques in automated reasoning rely on formal logic and mathematical principles to ensure sound and complete reasoning processes. As the field progresses, it increasingly integrates machine learning and other advanced AI technologies to tackle more sophisticated and abstract problems, pushing the boundaries of what automated systems can achieve. This book contains some path-breaking studies in the field of automated reasoning. This book explores all the important aspects of computer science in the present day scenario. Those in search of information to further their knowledge will be greatly assisted by this book.
