Alternative methods future trends

The chapter is organized as follows. We firstly describe models which are suitable for audio signal restoration, in particular those which are used in later work. Subsequent sections describe individual restoration problems separately, considering the alternative methods available to the restorer. A concluding section summarizes the work and discusses future trends. 

Abstract This contribution focuses upon the application of evolutionary algorithms to the non-deterministic polynomial hard problem of global cluster geometry optimization. The first years of method development in this area are sketched briefly followed by a characterization of the current state of the art by an overview of recent application work. Strengths and weaknesses of this approach are highlighted by comparison with alternative methods. Last but not least, current method development trends and desirable future development directions are summarized. 

The thematic treatment in this book differs somewhat from that of other works on this subject, and thus may serve as a supplement to other books. Our object was not to write an encyclopedic work on pesticides and their characteristics. Rather, we discuss mainly those active substances in pesticides which are of practical significance, may be of possible future importance, or represent research results and interesting trends. With regard to the latter, compounds are also discussed which are not on the market but represent promising new types. Ample space has been devoted to alternative methods of plant protection, e.g., insect growth regulators, sterilants and pheromones, which show promise for control of insect pests.
