17  This predicate should be implemented such that


18  <ul>


19  <li>For all b1 and b2, either b1 ≥ b2 or b2 ≥ b1.


20  <li>b ≥ b (every bid is better or equal to itself)


21  <li>If b1≥b2 and b2≥b1 then the two bids are considered


22  equally good. Note that this differes from a partial order in


23  mathematics.


24  <li>it behaves transitive: if b1≥b2 and b2≥b3 then


25  b1≥b3.
