In the past few days, due to work needs, the DBSCAN clustering algorithm has been implemented in C ++. Time complexity O (n ^ 2) is mainly used to calculate the points in each vertex field. The algorithm is very simple. Now I want to share your

All the tables add ' datatsp and Datatsp_int '--select * from sysobjects where xtype= ' you ' ORDER by name--database all have only one primary key table to add ' datatsp and Datatsp_int ' declare @table_name varchar (), @sql varchar (8000),

Dbscan is a density based clustering algorithm, its basic principle is given two parameters, ξ and MINP, where ξ can be understood as a radius, the algorithm will look for a sample in this radius, MINP is a ξ for the radius of the number of samples
