Computer has become an indispensable tool in solving complex problems in every sector. With the advent of digital computers, several fields have discovered the potential of employing computers' capacities in storage, computation, and simulation. The computation era has exploded and generated new research areas that go beyond all expectations. The application of computational tools to all areas of knowledge is producing excitements and insights into problems too complex for conventional approaches. Computation has become an integral part of a larger revolution that will affect how research is conducted. It will have a profound impact on many facets of our life, including advances in biology, medicine, energy conservation, and national security. Computation in different areas have led to various computational schemes such as computational engineering, computational electromagnetics, computational physics, computational biology, computational chemistry, computational electrodynamics, computational fluid dynamics, computational art, computational finance, and many other computational schemes. Many of these schemes have been developed into commercial software packages that make computation easy. Computation is commonly regarded as the third pillar of scientific investigation, complementing theoretical analysis and laboratory experiment. Computational tools have successfully been used to simulate complex problems that would be difficult if not impossible to handle using analytical methods. The success of these computational tools will be determined by their effectiveness in solving real-world problems of interest to society. This book explores emerging trends in computation. It is organized into three parts and 20 chapters that summarize various computation schemes. The book provides an overview of each emerging computational scheme in a way that beginners can understand. It is a must-read for those interested in computation and its future
