Method Detail |
---|
void bestSolutionChanged(BestSolutionChangedEvent<SolutionG> event)
Solution
is found.
The Solution
is guaranteed to be initialized.
Early in the solving process it's usually called more frequently than later on.
Called from the solver thread.
Should return fast, because it steals time from the Solver
.
In real-time planning
If Solver.addProblemFactChange(ProblemFactChange)
has been called once or more,
all ProblemFactChange
s in the queue will be processed and this method is called only once.
In that case, the former best Solution
is considered stale,
so it doesn't matter whether the new Score
is better than that or not.
event
- never null
