| Abstract: | In four-dimension assimilation,combining conjugate gradient metnod and genetic algorithms(DA) could remedy the shortcoming of each other.It is proved in the experiments of this papar that the scheme not only could strengthen searching ability but also could accelerate the convergent speed of optimization.We adopt standard program in programming,therefore the assimilation program is almost automatic,so we could be eased from the hard programming work and avoid most of the errors. |
| Keywords: | genetic algorithm conjugate gradient method four-dimension assimilation |
