| 4. | In theory , the method of math optimization can assure the global optimization result , but in fact it will result in the combination blast when the dimension increased 数学优化理论,从理论上保证得到全局最优解,但是在实际应用中,随着维数的增多将导致严重的“组合爆炸”问题。 |
| 5. | Some relative technical constraints have been considered , such as power balance , hydro / thermal power balance , construction start and power commencement date 以电源投资费用等年值最小为目标函数,结合相关技术约束(电力平衡、水火电平衡、电源投产电厂开工时间)条件,克服了组合爆炸问题。 |
| 6. | It is verified that this method enables scheme solving to be implemented with a better operability , which offers a promising way to solve combinatorial explosion problem in conceptual design 研究表明,该方法是合理可行的,它可以使方案求解的人工寻优过程实现算法化,并具有较好的可操作性,从而为解决方案优化的组合爆炸问题提供了一种新的思路。 |
| 7. | Compared with the conventional methods , assembly planning sequence based on polychromatic sets excludes the unreasonable assembly sequences in advance to avoid the exponential explosion due to the expansion of constrain relation 与传统的装配序列规划方法相比,基于多色集合理论的装配序列规划方法通过装配约束关系方程,提前排除了不合理的装配序列,因此避免了由约束信息膨胀产生的组合爆炸。 |
| 8. | For the sake of avoiding the resultant explosion during the course of process generation caused by considering too much factors , the idea is raised that it is feasible to regard workshop resource attribute as two parts ? the static and the dynamic which are considered at different step 为了使多工艺方案在创成过程中避免因考虑因素过多而产生的组合爆炸问题,本文提出将车间资源属性分为动态和静态两部分,在不同的工艺设计阶段分别加以考虑。 |
| 9. | A popular solution toimprove the speed and scalability of the association rule mining is todo the algorithm on a random sample instead of the entire database . buthow to effectively define and efficiently estimate the degree of errorwith respect to the outcome of the algorithm , and how to determine the samplesize needed are entangling researches until now . in this paper , an effective and efficient algorithm is given based on the pac probably approximate correct learning theory to measure and estimatesample error 关联规则挖掘作为数据挖掘的核心任务之一,由于其任务本身的复杂性通常需要多次整个扫描数据库才能完成挖掘任务且频繁模式可能产生组合爆炸,使得从原始的大规模数据集上抽取一部分样本,在其上寻找用户感兴趣的近似规则成为目前提高算法效率和可扩展性的一种简单有效的现实可行方法之一。 |
| 10. | Specialist system faces many problems and difficulties , such as knowledge acquirement depends on manual transplantation which leads to high cost and low efficiency ; applying general clarified set brings forward with feeble reasoning ability , matching collision and combination explosion . nowadays modern intelligent control focuses on fuzzy logic and neural networks or the combination of the two 由于专家系统在实际应用中有较多的问题和困难(如:知识的获取主要靠人工移植,因此成本高、效率低;采用常规的分明集,致使它的推理能力弱,容易产生匹配冲突、组合爆炸等问题) ,现在智能控制的重点则集中在模糊逻辑、神经网络以及二者的结合应用上。 |
