A DNA genetic algorithm with reconstruct operator for chemical process modeling
2011
A DNA genetic algorithm with reconstruct operator (rDNA-GA) is presented in this paper. In the proposed algorithm, potential solutions of the problems are represented as individuals with nucleotide bases, and genetic operators inspired by DNA operations are adopted over the individuals. Among the genetic operators, reconstruct operator is a new operator which is used to improve the diversity of the population through reconstructing the similar individuals of the population. The simulation results of two test functions show that rDNA-GA outperforms another method, AGA. Finally, rDNA-GA is used to estimate the parameters of a chemical engineering process, the hydrogen reaction models. And the result shows the effectiveness of the proposed algorithm compared with other reported models obtained by other algorithms.
