Pastor's discovery of a historical example of a noninferior fractional
solution to the location set-covering problem is not unexpected. We a
rgue here that a method or observation that is generally good (or true
) has merit and should not be dismissed as lacking in utility because
of occasional counterexamples. A further report concerning fractions/i
ntegers in set-covering problems is made and the specific example cite
d by Pastor is analyzed.
