Sorting algorithm is one of the most basic research fields in computer science. It's goal is to make record easier to search, insert and delete. Through the description of five sort algorithms: bubble, select, insert, merger and quick, the time and space complexity was summarized. Furthermore, two categories of O(n2) and O(nlog n) could be found out. From the aspects of input sequence scale and input...
As a practical method for knowledge reduction, discernible matrix (DM) has been widely used in practice. However, due to the high cost of constructing and reducing of a matrix, the efficiency of this method falls far short of people's demands. In order to decrease the cost of knowledge reduction based on the ideas of set theory, the paper presents a new approach, which is called the minimum discernible...
This paper firstly introduced the traditional LSB information hiding scheme, then proposed an improved LSB algorithm. This algorithm implements the information by many kinds of transformation. Theoretical analysis and experimental results demonstrate that the information hiding scheme can effectively resist both RS and statistics analyses, and improve the security of traditional LSB scheme.
With the rapid development of national e-commerce economy in China, logistics has gained more high speed of development and abstracted more attentions as "the third profit source". Large-scale production companies and commercial enterprise have set up their own distribution center. The development of the traffic logistics has brought more efficiency of commodity circulation along with some...
