CVT_MAIN
   A sample problem for the probabilistic
   Centroidal Voronoi Tesselation algorithm.
  
   Today's date: 20010423
   Today's time: 095554.493
  
   Given a region in 2D or 3D, the problem is to determine
   GENERATORS, a set of points which define a division
   of the region into Voronoid cells, which are also CENTROIDS
   of the Voronoi cells.
  
  
 Geometry parameters:
 -------------------
  
   The spatial dimension is NDIM =            3
  
   The minimum corner of the bounding box is:
  0.000000000000000E+000  0.000000000000000E+000  0.000000000000000E+000
   The maximum corner of the bounding box is:
   100.000000000000        100.000000000000        20.0000000000000     
  
   DIATOM is not called;
   a simple routine determines the region.
  
 CVT Algorithm parameters:
 -------------------------
  
   The number of Voronoi cells to generate:        50000
   Number of iterations to determine CVT:            1
   Number of sampling points per Voronoi cell:          100
   Voronoi cell generators are initialized by Halton.
  
  
 Moment parameters:
 ------------------
  
   Number of sampling points per Voronoi cell:          100
  
   The volume of the region is given.
   It is specified as REGION_VOLUME =    34000.0000000000     
  
  
 Nearest Neighbor Search parameters:
 -----------------------------------
  
  
   The nearest neighbor search is speeded up by using bins.
   The bounding box is to be divided up into bins.
   The number of bins is :          25          25           5
  
  
 Miscellaneous parameters:
 ------------------------
  
   Generator and moment output files will NOT be written.

 BIN_PREPROCESS:
  
   Number of points =            50000
   Total number of bins =         3125
   Number of empty bins =         2403
           nonempy bins =          722
  
   Percentage nonempty bins =            23.10400    
   Number of points per bin =            16.00000    
   Number of points per nonempy bin =    69.25208    
  
   Volume of bounding box is        200000.000000000     
   Given volume of region is        34000.0000000000     
   Estimated volume of region is    33961.5841503189
