9.7. Strongest Fit Decreasing
9.7.1. Algorithm Description
Combines First Fit Decreasing and Strongest Fit. So it sorts the planning entities on decreasing difficulty and the planning values on decreasing strength.
Requires the model to support planning entity difficulty comparison and planning value strength comparison.
Do not presume that this algorithm has better results than First Fit Decreasing or Weakest Fit Decreasing. That’s often not the case. However, it is usually better than Strongest Fit.
9.7.2. Configuration
Configure this solver phase:
<constructionHeuristic>
<constructionHeuristicType>STRONGEST_FIT_DECREASING</constructionHeuristicType>
</constructionHeuristic>
If the InitializingScoreTrend is ONLY_DOWN, this algorithm is faster: for an entity, it picks the first move for which the score does not deteriorate the last step score, ignoring all subsequent moves.
For advanced configuration, see Allocate Entity From Queue.
