The goal of this chapter is to introduce the key algorithms and theory that constitute the core of Evolutionary computation. The principles and foundations of a basic genetic Algorithm are described in detail. In addition, a separate section discusses extensions to the simple Genetic Algorithm, such as reened crossover, mutation and selection schemes. and real coded representations. The chapter...

| Adaptation of parameters and operators is one of the most important and promising areas of research in evolutionary computation; it tunes the algorithm to the problem while solving the problem. In this paper we develop a classiication of adaptation on the basis of the mechanisms used, and the level at which adaptation operates within the evolutionary algorithm. The classiication covers all fo...

We evaluate the convergence speed of an Interactive Evolutionary Computation (IEC) using a rating-scale mapping for user fatigue reduction. First, we introduce the concept of mapping users' relative ratings to an “absolute scale”; this allows us to improve the performance of the IEC subjective evaluation characteristic predictor, which can in turn accelerate EC convergence and reduce user fatig...

World Wide Web is growing at a very fast pace and makes a lot of information available to the public. Search engines used conventional methods to retrieve information on the Web; however, the search results of these engines are still able to be refined and their accuracy is not high enough. One of the methods for web mining is evolutionary algorithms which search according to the user interests...

The lack of a social context is a drawback in current Interactive Evolutionary Computation systems. In application areas where cultural characteristics are particularly important, such as visual arts and music, this problem becomes more pressing. To address this issue, we analyze variants of the traditional Interactive Evolutionary Art approach – such as multi-user, parallel and partially inter...

In this paper we describe how we have developed an application that is capable of evolving melodies with some human help to guide it. We have developed this system using evolutionary algorithms and interactive evolution. The user can use the application to, first, evolve short blocks of notes, and second, to combine these blocks into longer melodies using more evolutionary techniques. The resul...

Today, researches for singing by computer have attracted attention. VOCALOID is an application to realize that aim. By inputing lyrics and melody, users can make songs sung by the computer. In order to make the singing voice more human , users must control frequency curve very carefully. Comparing with inputing lyrics or melody, this controlling presents heavy overhead for users. In this resear...
