/***************************************** * Graph Partition Program * * This software implements the graph partition algorithm in * "Graph Partitioning with Natural Cuts, Daniel Delling etc., IEEE International Parallel & Distributed Processing Symposium, 2011". * * Author: Yu Sun, Nanyang Technological University * Last update date: 18th Jan. 2013 ******************************************/ Use the following three steps to run the software: ---------------------------- 1. '%D:\SPV\GraphPartition\BIN>'Preprocess.exe ..\data\USA-road-d.NY.gr ..\data\USA-road-d.NY.new.gr 2. '%D:\SPV\GraphPartition\BIN>'Filter.exe 4096 ..\data\USA-road-d.NY.co ..\data\USA-road-d.NY.new.gr ..\result\NY\ 3. '%D:\SPV\GraphPartition\BIN>'Assemble.exe 4096 ..\data\USA-road-d.NY.co ..\data\USA-road-d.NY.new.gr ..\result\NY\anode.txt ..\result\NY\aedge.txt ..\result\NY\ ---------------------------- The result is written in two files in the given output folder (..\result\NY\ in the above example): 'cut_edges.txt' and 'node_clusters.txt'. The format of the result file is self-explanatory. The format of the input file follows that of the '9th DIMACS Implementation Challenge - Shortest Paths', and the datasets can be downloaded from http://www.dis.uniroma1.it/challenge9/download.shtml. Some sample files are in the \data folder. Note that the \result\NY\ folder needs to be created manually. ========================================================= Details: The first step is to remove duplicated edges, which is necessary. The parameters for Preprocess.exe is ---------------- <arg1> input file name (including path) <arg2> output file name ---------------- The second step is the Filter phase, and its parameters (in this order) are ----------------------- <arg1> U node size limit <arg2> node file path, e.g. C:/GraphPartition/data/node.txt <arg3> edge file path, e.g. C:/GraphPartition/data/edge.txt <arg4> result file directory, e.g. C:/GraphPartition/data/result/ <arg5> (optional) C detect natural cuts times, default 1 <arg6> (optional) f sets the core size relative to the ring, default 10 ----------------------- The third step is the Assemble phase. Its parameters are ----------------------- <arg1> U node size limit <arg2> original node file path, e.g. C:/GraphPartition/data/node.txt <arg3> original edge file path, e.g. C:/GraphPartition/data/edge.txt <arg4> assemble node file path, e.g. C:/GraphPartition/data/anode.txt <arg5> assemble edge file path, e.g. C:/GraphPartition/data/aedge.txt <arg6> result file directory, e.g. C:/GraphPartition/data/result/ <arg7> (optional) FI each pair failure time, default 16 <arg8> (optional) M multistart trying time,default 1 <arg9> (optional) use combination Y/N, default N ----------------------- To visualize the result, use the showResult.html in the showResult folder.
