org.optaplanner.core.config.score.trend.InitializingScoreTrendLevel
- All Implemented Interfaces:
Serializable
,Comparable<InitializingScoreTrendLevel>
Bounds 1 score level of the possible
Score
s for a PlanningSolution
as more and more variables are initialized
(while the already initialized variables don't change).- See Also:

No predictions can be made. -
ONLY_UP
During initialization, theScore
is monotonically increasing. This means: given a non-fully initializedPlanningSolution
with aScore
A, initializing 1 or more variables (without altering the already initialized variables) will give aPlanningSolution
for which theScore
is better or equal to A.In practice, this means that the score constraints of this score level are all positive, and initializing a variable cannot unmatch an already matched positive constraint.
Also implies the perfect minimum score is 0.
-
ONLY_DOWN
During initialization, theScore
is monotonically decreasing. This means: given a non-fully initializedPlanningSolution
with aScore
A, initializing 1 or more variables (without altering the already initialized variables) will give aPlanningSolution
for which theScore
is worse or equal to A.In practice, this means that the score constraints of this score level are all negative, and initializing a variable cannot unmatch an already matched negative constraint.
Also implies the perfect maximum score is 0.
