it hasn't been done so far as I know but it certainly is possible.
there are functions for removing connections so pruning is easy --
there is a "PruneCons" routine for removing connections as a function
of weight values already.

all the algorithm code is compiled c++ and should run as fast as
possible, tho using vectors instead of objects & pointers for
connections is faster, but significantly less flexible.., it also
includes a script language that compiles into an object-oriented
"machine" that is actually run.
