    The genetic algorithm has good searching performance, but it is prone to “premature”. A two-stage composite genetic algorithm is proposed based on genetic algorithm. The first stage of the new algorithm is used to search in the global solution space, according to the results of the first stage and range reduction strategy, searching of the second stage is based on a satisfactory space and more accessible to the optimization solution to avoid local optima trap. Compared with other improved genetic algorithm by simulation examples, the proposed algorithm is proved better commonality.

    In text classification, only a few scholars used the weight of feature words to express text, but the method of feature selection they used didn’t consider the symbol and boundary of the weight of feature words. So, on the basis of CHI statistics, this paper proposes a new way to calculate correlation-score between feature words and classification; and selects different means to get the relevance between text and classification, according to the count of feature words in each feature set. At last, in order to determine the text category, this paper just applies the number of feature words and their relevance to category, and can well judge the text contained few feature words. Experiment shows that it is an effective and feasible method to classify text.

At first median filtering is used to remove the noise because it can protect the edge of the image at the same time. Secondly, gradient sharpening is employed to enhance the strength of the edge pixels, then the initial edge of the image is obtained by simple binarization. The system uses a connected component labeling method to remove the residues black block within the enclosed boundaries of the image. Finally, by comparing the results of the experiment with the manual extraction results and error analysis, the shortcoming of this algorithm is found for future work. Practice has proved that the edge detection method of this paper has a good effect to speckle images.
