[GIS program] ttt DL : 0: 本人载网站开发gis,游自编的最短路径查询程序，速度特快，3万节点，35000条路全部遍历，只需1秒。现将最短路径的思路告诉大家，希望大家在优化，并用不同语言编制，我正在学delphi,准备用delphi做成库，本例以由拓扑关系的arc/info 文件为数据源。其中a1,b1,c1是以fnode排序生成的数组，a1对应fnode,b1对应tnode,c1对应length,同样a2,b2,c2,是以tnode 生成的数组。Indexa1是对应某一起点与其相连的终点的个数，indexb1时对应某一终点与其相连的起点的个数，即其拓扑关系。-I set website development gis, shortest path traveled own inquiry procedure, the speed of an express, 30,000 nodes, 35,000 all ergodic Road, just 1 second. The idea of the shortest path to tell everybody, I hope everyone in the optimization, and use different languages, I was learning delphi, made ready to use delphi library, in this case by the topological relations between the arc/info file for the data source. Which a1, b1, c1 is generated fnode array sort, a1 corresponding fnode, b1 corresponds tnode, c1 corresponds to length, the same a2, b2, c2, is generated tnode array. Indexa1 is a starting point corresponding to its number of connected endpoints, indexb1 corresponds to a particular destination when its connected to the starting point for the number, that is, their topological relations.

[GIS program] 4_bit_swap DL : 1: Logisim四位排序器先使用1位的swap搭建4位的swap，再使用4位的swap模块和Logisim内置的comparator元件搭建排序电路(请不要使用Plexers类元件) 功能描述:该电路具有4个4位的二进制数字作为输入和4个4位的二进制数字作为输出。它的功能是，将4个输入的二进制数字进行排序，从上往下数第一个输出端口输出的是4个数字中最小的，第二个输出端口输出的是第二小的，以此类推。输入： A,B,C,D(4bit) 输出： #1,#2,#3,#4(4bit)(#1对应第一个输出端口，以此类推) 文件内 1 位swap模块名: 1bit_swap 文件内 4 位swap模块名: 4bit_swap 文件内排序电路模块名: 4bit_sort(Logisim four bit sorter Build a 4-bit swap using a 1-bit swap, and a sort circuit using a 4-bit swap module and a built-in comparator component in Logisim (do not use Plexers class components) Function Description: The circuit has four 4-bit binary digits as input and four 4-bit binary digits as output. Its function is to sort the four input binary digits. The output from the first output port is the smallest of the four digits, the output from the second output port is the second smallest, and so on. Input: A, B, C, D (4bit) Output: #1, #2, #3, #4 (4bit) (#1 corresponds to the first output port, and so on). The 1 bit swap module name in the file is 1bit_swap The 4 bit swap module name in the file is 4bit_swap File sorting circuit module name: 4bit_sort)
