描述.This book presents a set of theoretical and experimental results that describe the features of the wide family of α-stable distributions (the normal distribution also belongs to this class) and their various applications in the mutation operator of evolutionary algorithms based on real-number representation of the individuals, and, above all, equip these algorithms with features that enrich their effectiveness in solving multi-modal, multi-dimensional global optimization problems. The overall conclusion of the research presented is that the appropriate choice of probabilistic model of the mutation operator for an optimization problem is crucial..Mutation is one of the most important operations in stochastic global optimization algorithms in the n-dimensional real space. It determines the method of search space exploration and exploitation. Most applications of these algorithms employ the normal mutation as a mutation operator. This choice is justified by the central limit theorem but is associated with a set of important limitations. Application of α-stable distributions allows more flexible evolutionary models to be obtained than those with the normal distribution. The book prese

Stable Distributions,rectly useful for the analysis of stable distribution applicability to evolutionary processes. At the beginning, the definition of the stable random variable, as well as its characteristic function, is given. A series of theorems which describe the properties of the stable random value is presented,

Non-isotropic Stable Mutation,nt individual a normally distributed random value. Mutations in phenotypic evolutionary algorithms (see Chap. .), like evolutionary programming (Table .), evolutionary strategies (.) and evolutionary search of soft selection (.), are typical realizations of the above approach. Therefore, the most na

Stable Mutation with the Discrete Spectral Measure,vector . and . is a localization vector. Therefore, the application of multidimensional stable distributions to global optimization tasks is limited to two simple cases. One is (described in Chap. .) the non-isotropic stable distribution ., for which the spectral measure is generated by points lying

Isotropic Mutation Based on an ,-Stable Generator,o our purpose, which is the elimination of the dead surrounding effect. This conclusion stems from the fact that the random variable ., where ., depends only on the generating variable . and not on the space dimension . (or a proof, see (.)). Also, we hope that this fact weakens the dead surrounding

Conclusions, observed phenomena, we want to discover laws governing them in order to use those in designed methods and algorithms. One of the most interesting phenomena is the evolutionary process, which is an invaluable property of nature. Thanks to this process, very complex organisms, which are adapted to al

Non-isotropic Stable Mutation,tural application of .-stable distributions to the mutation operation is exchanging the additive Gaussian disturbance of each component . of a parent vector by a random variable of the symmetric .-stable distribution . (one can calculate such a random variable based on Theorem .), which is controlled by the scale parameter ..
