Given a list of objects with attributes a0, a1, a2,....an-1 is there an
efficient way to find sets of attributes which can be used to distinguish
members of the list?
As example a list of people might have
firstName, lastName, nationality, postcode, phonenumber,....
as attributes. The probe items may have some of these attributes, but which
should be used to test. Presumably the information in any attribute is highest
if the number of distinct occurrences is the the same as the list length and
pairs of attributes are more likely to be unique, but is there some proper way
to go about determining what tests to use?
A particular problem might be dynamic in that the list may be being constructed
from the probes.
