Genetic algorithm method

In the present study, we propose a tuning method for PID controllers and apply the method to control the PBL process in LG chemicals Co. located in Yeochun. In the tuning method proposed in the present work, we first find the approximated process model after each batch by a closed-loop Identification method using operating data and then compute optimum tuning parameters of PID controllers based on GA (Genetic Algorithm) method.

While different types of bioinformatics tools can be used to discriminate samples based on their source, the initial paper by Petricoin and Liotta used ProteomeQuest , a software tool developed by Correlogics of Bethesda, Maryland. This software combines elements from genetic algorithm methods and cluster analysis. For the analysis of mass-spectral data, each of the input files is composed of m/z values on the x axis along with their corresponding amplitudes on the y axis. The output of the algorithm is the most robust subset of amplitudes at dehned frequency values that best separates the preliminary data acquired from the samples obtained from either healthy or diseased patients [21].

A third approach is based on the application of genetic algorithm methods to the study of the evolutionary development of a reaction mechanism, to the attainment of given goals (flux control, for example) in a mechanism, and to the determination of a reaction mechanism and rate coefficients by comparison with experiments.

Zhao et al. compared the structures of Si and Ge clusters for 25 < n < 33. They used an unbiased approach for identifying the structures of the global total-energy minima. This approach is based on a genetic-algorithm method combined with a parameterized tight-binding method. From the calculations they obtained a pool of 20 candidate structures. Subsequently, parameter-free, density-functional calculations were performed for those 20 structures, that then were allowed to relax locally.
