'This book illustrates the methods developed in artificial intelligence for search, learning, problem solving and decision making. This gives an idea of the algorithm and architecture of artificial intelligence that has reached the degree of maturity when the method can be presented as an algorithm, or when good architecture must be known, for example It can be used as a textbook for a broad audience of application developers interested in using intelligence methods artificial in their software products. Part of the text is somewhat independent, so that someone can look into the index and directly to the description of the methods presented in the form of an abstract algorithm or solution architecture.
