Dear Winfried:

I was about to go home when I noticed that the updated version 
finished all my examples. 

One of the examples I did have problems (to get an answer) with the 
previous version is below (I left it running for several days and 
did not finished). With the new version it took around 20 
minutes.

Thanks (to both of you) for improving the algorithm. 

Best for 1998
Regards,
Rafael
