Counting the number of base cases can be done one of two ways:

 - Add a variable to NeighborSearchRules (or whatever ruleset you are
   considering) which is incremented each time a base case is computed.
   Then when the traversal is complete, print that variable.

 - Compile with profiling and debugging options (so that BaseCase()
   isn't inlined) and then take a look at the output of gprof:

   gprof bin/allknn gmon.out | less

   (or something like that) and you should be able to see how many times
   BaseCase() was called.

Does this answer your question?
