This paper considers games with perfect information and randomly changing coalitional partitions in some fixed vertices of the game tree. An algorithm for constructing the optimal subtree is proposed and the new value (the so called PMS-value) for such games introduced.
本文中考虑了具有完全信息的对策,并且在对策树的一些固定结点处随机地改变联盟分割,从而形成了构造最优子树的算法,针对这样的对策同时也得到了一种新值。

The phylogenetic trees supported that Eriocaulaceae be treated as Eriocaulales because this family always been a nature independent group connected with other families. Eriocaulaceae grouped with Commelinaceae, which supported the close relationship and parallel evolution between the two families. Juncaceae was not close to Eriocaulaceae and more primitive. The relationship between Juncaceae and Cyperaceae was closer than that between Juncaceae and Poaceae. Among these families, Poaceae was the most primitive family and far from Eriocaulaceae. Also in Eriocaulaceae, Eriocaulon was supported to be more primitive.
从构建的系统发育树可以得到:①谷精草科独立形成一个植物类群,支持谷精草科独立成为谷精草目;②谷精草科与鸭跖草科聚成一个大的类群,说明两科的亲缘关系较近,并且表现为平行进化;③灯心草科不近缘于谷精草科,与禾本科相比,灯芯草科与莎草科之间存在更近的亲缘关系;④在进化程度上,灯心草科比谷精草科原始;禾本科与谷精草科的亲缘关系最远,并且在这几个科中处于最原始的进化地位;⑤系统树还支持谷精草科内部的系统关系,支持谷精草属在谷精草科中的原始系统位置。

More than 10 years ago,when the Taishan Mountain scene was under busy construction which is their most brilliant times.During that period of time,there were 300 to 400 porters shuttling up and down on the steep and twisted stages with an orgy of work.However,with the scenery of Taishan Mountain being perfected,tshe porters lacked scope of their abilities gradually,especially the completement of the tramway.Most of them left there for a new life without any other choice,but only a few still decided to stay.

The algorithm needn't generate candidate itemsets and scan database, because it employs FP-Tree to store trasanctions in database compressedly and takes full advantage of the characteristic of FP-Tree.Consequently,the complexity of space and time the algorithm used is reduced obviously in the procedure of data mining.In a thorough experimental analysis of our algorithm on real and synthetic data,we isolate the effect of the individual components of the algorithm. Our performance numbers show that MFP-Miner outperforms previous work.
该算法利用频繁模式树来压缩存储数据库中的事务,并充分利用频繁模式树的特点,在挖掘最大频繁项目集的过程中不需要产生候选项目集和扫描数据库,从而减少了算法在挖掘过程中使用的存储空间和计算时间,通过实验结果显示,该算法的性能优于同类算法。

Are countable sets:Λ-Γ,〓-Γ are either empty or countably infinite, where Γ denotes the set of γ-limit points of f; tree map's depth of attracting center is finite and the attracting center is Γ provded all the branching points are periodic points. In chapter Ⅲ. we discuss certain relationship between isolated chain recurrent point and eventually periodic point of some continua.
主要利用树的特殊偏序关系证明了:不在周期点集闭包中的ω极限点都有无限轨迹;Ω-〓,Ω-Γ为可数集,Λ-Γ,〓-Γ或为空集或可数无限,其中Γ为f的γ极限点集;当分支点都是周期点时,连续树映射的吸引中心深度有限,且吸引中心就是Γ。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
