Method Details
-
bestSolutionChanged
Called once every time when a betterPlanningSolution
is found. ThePlanningSolution
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.addProblemChange(ProblemChange)
has been called once or more, allProblemChange
s in the queue will be processed and this method is called only once. In that case, the former bestPlanningSolution
is considered stale, so it doesn't matter whether the newScore
is better than that or not.- Parameters:
event
- never null
