This program is the application of CLIQUE clustering algorithm on 2-dimentionalspatial data. This program does not realize CLIQUE's idea of selecting potential dense 2-dimentinonal cells from dense 1-dimentional cells because this idea does notapplicable to our testing data sets. This program just realized CLIQUE's clusteringalgorithm, connecting neighbouring dense cells into one cluster, in 2-dimentionaldata set.The usage of the program is like this:"clique fileName numberOfPoints resolution xmin xmax ymin ymax tau"where the meaning of each argument is:fileName -- data file namenumberOfPoint -- the number of data points in the data fileresolution -- resolution in clusteringxmin -- minimum in x-axisxmax -- maximum in x-axisymin -- minimum in y-axisymax -- maximum in y-axistau -- threshold in determining dense cellsone example of the usage of the program is like:clique t7.dat 10000 20 0 700 0 500 0.18
