| Abstract: | In the paper, the development course of displacement algorithm is illustrated firstly. Then, on the basis of analyzing all kind of displacement algorithms, the algorithm are reduced and divided into seven classes. As to every class of algorithm, its main thought is illustrated in detail. At last, every class of algorithm is analyzed and evaluated, and its advantages and disadvantages are listed out. The good algorithm and thought are summed u Pin order to improve the development of displacement. |
