Hello ,

a) sometimes I like (or better : try ..) to construct some
help-mate-problems --
unfortunately it is (being "human") sometimes awfully difficult to
prove that only
one solution exists ...

b) are there any help-mate-programs which could do such "proof-reading" ?!
and where can one get them ?!

c) thanx for any hint (and of course : "nice 2004") Ö
