The number of segments is automatically computed due to the inherent heuristic searching. 用启发式搜索方法自动获取最佳分段数。
The heuristic searching algorithm maximizes the fitness of the additional constraint set, thereby reaches the final result that can satisfy the user's expectation. 通过启发式搜索算法使增加的额外约束得到最大化满足，从而寻找到符合用户意图的解。
