the system chose

After analyzes of several shortest path algorithms, the system chose the Dijkstra algorithm as the based algorithm.Although the use of Dijkstra algorithm will be the optimal solution, but because it includes a lot of computing nodes, the efficiency is lower. For improving the computation speed of the system to optimize, that to make it adapted to digital maps polo shirts Web GIS better which has the characteristics of a large quantity computing. When we completely use the Dijkstra algorithm, there are a lot of useless calculation, there has been a lot of the infinite value. The same as the Dijkstra algorithm and optimize Dijkstra algorithm of the process, and that will be omitted the infinite value for the calculation, so this will greatly reduces the space complexity of algorithm to improve the women's nike shoes computational efficiency.Through the optimization of the algorithm can improve the speed of algorithm for computing in some extent. But when face to the actual city road, substantial cheap ralph lauren polo shirts amount of data computing time is still not high. On the basis of that, this paper use the hierarchical search algorithm, which can reduce the layer that is not concerned, and the targeted analysis of discount wedding dresses relevant layers will reduce the system response time. As well as using the custom made prom dresses regional restriction can reduce the search area in order to reduce computation algorithm and improve response time. The best path selection algorithm of users to travel, according to the different needs of users on the road re-assigns the right value.In this thesis, we analyzed and compared the restricted area of the plus size wedding dresses oval, the rectangular, the fan, and the combination of round and rectangular,. And they all have their own advantages and disadvantages.
