Computers have permeated almost every facet of modern chess, yet few players know how to gain the maximum benefit from working with them. Computers function as playing partners, opening study tools, endgame 'oracles', tactics trainers, sources of information on opponents and searchable game databases. Kongsted provides practical advice on how to use computers in all these ways and more. He also takes a look at the history of the chess computer, and how its 'thinking' methods have developed since the early days.

This book will enable readers to handle various EMC problems, to develop their own EMC computational models in applications in research and industry, and to better understand numerical methods developed and used by other researchers and engineers not only in EMC, but in other areas of engineering. For example, students and engineers can use the calculation methods for the radiation of base station antennas for planning the location of GSM and UMTS base stations and for the human exposure assessment based on material covered.
