Method Detail |
---|
S getPerfectMaximumScore()
Score
is the Score
of which there is no better in any problem instance.
This doesn't mean that the current problem instance, or any problem instance for that matter,
could ever attain that Score
.
For example, most cases have a perfect maximum Score
of zero, as most use cases only have negative
constraints.
S getPerfectMinimumScore()
Score
is the Score
of which there is no worse in any problem instance.
This doesn't mean that the current problem instance, or any problem instance for that matter,
could ever attain such a bad Score
.
For example, most cases have a perfect minimum Score
of negative infinity.
