7 | Defines a is-better relation between bids. This basically is a partially
|

8 | ordered space however some bids or groups of bids may not be relatable to
|
---|
9 | others.

13 | @param bid1 the first item's utility/preference

14 | @param bid2 the second item's utility/preference

15 | @return true iff bid1 is considered better or equal (≥) than bid 2. In

16 | all other cases false is returned. A bid may not have a ≥

19 | This predicate should be implemented such that
|
---|
20 | <ul>
|
---|
21 | <li>b ≥ b (every bid is better or equal to itself)
|
---|
22 | <li>If b1≥b2 and b2≥b1 then the two bids are considered
|
---|
23 | equally good. Note that this differes from a partial order in
|
---|
24 | mathematics.
|
---|
25 | <li>it behaves transitive: if b1≥b2 and b2≥b3 then
|
---|
26 | b1≥b3.
