Hi All


I'm trying to experiment with modifications to DL-Learner initially by experimenting with different Refinement Operators. To get the ball rolling, I copied RhoDRDown.java and:

- changed the name to MpbVersion1 and adjusted the annotation to "mpb" (where previously there was "rho")

- included a reference to my new file in the "componentClassNames" list of AnnComponentManager.java

- then tried to run it by changing rho to mpb in an already-working con file.


However it does not work.  Any ideas how I can make it work? 


Thanks in advance,


Matthew
