Further Results on Constructing Asymmetric Covering Codes by Tabu Search,
submitted.

Asymmetric covering codes are given by their decimal value
(i.e. 11 in decimal is ...001011 in binary).
The covering code files list the codewords, the filename
contains the other relevalent information (length *N*, covering
radius *R* and cardinality *M*).

Excluding (n=12, R=4), these are just improvements to our earlier results (as we are not aware of other improvements) .
