[GRASS5] A question about v.surf.idw

[Muzaffer Ayvaz]

Hi;
   
  In main.c of v.surf.idw module in GRASS 6.0.1;
   
    /* Arbitrary point to switch between searching algorithms. Could do
  * with refinement PK */
  if( (window.rows*window.cols)/npoints > 400 )
   
  is written to select old ( brute force ) or new (clarke) algorithm.
   
  How did you decide the number 400? What is your test data or test function?
  Do you have an article about that?
   
  As much as I read from the articles whichs aouthor is Marc P. Armstrog Clarke's algortihm is always better for different data sets.
   
  Or is this a better way to define this number as an option for the user?
   
  Best regards
  Muzaffer...
