Originally published in 1998, this handbook describes the statutes and cases that defined the governance, control and authority of the provincial police forces in England and Wales at the time. For many years the complexity and range of these legal authorities had caused misunderstandings and doubt when differing aspects of police activities had been questioned. To clarify the law a major step was taken in the enactment of the Police Act 1996. The consolidating Act brought together most of the existing statutory provisions regarding the governance of police forces. However, since about 1980, a number of other factors relevant to the powers and control of the police had emerged, most notably: Increased civil litigation had led to a number of cases defining the civil liability of the police; Increased use of judicial review procedures with consequent case decisions defining police powers in particular circumstances; Greater centralisation in police policies together with the Home Secretary's control of finance and other matters; Increased police use of sophisticated technology for record keeping and surveillance purposes; The involvement of the security service in an anti-criminal role. The book (which includes illustrative charts) covers many complex legal issues. It has been written in a plain non-legalistic style. It is understandable to non-lawyers. However, for the benefit of practitioners, all statutory and case references are provided so that original materials can be consulted by those needing further information.

""Algorithms for Games"" aims to provide a concrete example of the programming of a two-person game with complete information, and to demonstrate some of the methods of solutions; to show the reader that it is profitable not to fear a search, but rather to undertake it in a rational fashion, make a proper estimate of the dimensions of the "catastrophe," and use all suitable means to keep it down to a reasonable size. The book is dedicated to the study of methods for limiting the extent of a search. The game programming problem is very well suited to the study of the search problem, and in general for multi-step solution processes. With this in mind, the book focuses on the programming of games as the best means of developing the ideas and methods presented. While many of the examples are related to chess, only an elementary knowledge of the game is needed.

Mihail Moiseevich Botvinnik is an electrical engineer by profession; during World War II he headed a high-tension laboratory in the Urals and was decorated by the USSR for his accomplishments. At present, he is the head of the alternating-current machine laboratory at the Moscow Institute of Power Engineering. He is also a world-renowned chess player. He was born in 1911, and by 1935 had become a Grandmaster of Soviet chess. In 1948 he won the world chess championship and held the title until 1963 (except for a two-year break). His chess style has been characterized as deep, objective, serious, and courageous. In this book, the quality of his thinking is revealed in his study of the basic thought processes of master chess players, and his reduction of these processes to mathematical form. This formalization of thought processes is a contribution to science at three levels: at the immediate level, it provides a basis for a computer program that seems likely to succeed in playing chess; at the middle level, game-playing programs help us to study and rationalize the processes of planning and decision-making; and, at the highest level, the study of the mind in action, as in the game of chess, leads to an understanding of human thought and of the human psyche.
