Modeling Dependencies of Loci with String Classification According to Fitness Differences

چکیده
Genetic Algorithms perform crossovers effectively when we can identify a set of loci tightly linked to form a building block. Several methods have been proposed to detect such linkage. Linkage identification methods investigate fitness differences by perturbations of gene values and EDAs estimate the distribution of promising strings. In this paper, we propose a novel approach combining both of them, which detects dependencies of loci by estimating the distribution of strings classified according to fitness differences. The proposed algorithm called the Dependency Detection for Distribution Derived from df (DDDDD or D) can detect dependencies of a problem which is difficult for EDAs requiring lower computation cost than linkage identifications.

Linear and Nonlinear Multivariate Classification of Iranian Bottled Mineral Waters According to Their Elemental Content Determined by ICP-OES
The combinations of inductively coupled plasma-optical emission spectrometry (ICP-OES) and three classification algorithms, i.e., partial least squares discriminant analysis (PLS-DA), least squares support vector machine (LS-SVM) and soft independent modeling of class analogies (SIMCA), for discriminating different brands of Iranian bottled mineral waters, were explored. ICP-OES was used for th...
متن کاملDrill string Vibration Modeling Including Coupling Effects
Abstract: The governing equations of motion for a drill string considering coupling between axial, lateral and torsional vibrations are obtained using a Lagrangian approach. The result leads to a set of non-linear equations with time varying coefficients. A fully coupled model for axial, lateral, and torsional vibrations of drill strings is presented. The bit/formation interactions are assumed ...
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
