In OR terms, this is called the upper bound if they minimize, and lower bound if they maximize. Because we always maximize the {@link Score}, calling it upper bound would be a contradiction. @param scoreDirector never null, use {@link ScoreDirector#getWorkingSolution()} to get the working {@link Solution} @param score never null, the {@link Score} of the working {@link Solution} @return never null, never better than the worst possible {@link Score} we can getby initializing the uninitialized variables of the working {@link Solution}.

            ScoreDirector scoreDirector = phaseScope.getScoreDirector();
            Score score = scoreDirector.calculateScore();
            startNode.setScore(score);
            ScoreBounder scoreBounder = decider.getScoreBounder();
            phaseScope.setBestPessimisticBound(startLayer.isLastLayer() ? score
                    : scoreBounder.calculatePessimisticBound(scoreDirector, score));
            startNode.setOptimisticBound(startLayer.isLastLayer() ? score
                    : scoreBounder.calculateOptimisticBound(scoreDirector, score));
        }
        if (!startLayer.isLastLayer()) {
            phaseScope.addExpandableNode(startNode);
