  • 简介:Multiway决定图(MDG)是排序许多的一阶的逻辑的一个子集的一个正规代表。这个子集与抽象类型和uninterpreted功能符号概括平等的逻辑。在抽象、具体的排序之间的区别反射在数据路径和控制之间的硬件区别。这里,我们认为方法改进MDG建设。效率通常通过Generalized-If-Then-Else(GITE)的使用被完成在二进制决定图包裹的操作员。因而,我们考察为MDG确认技术使用的主要算法。特别地,关系产品并且由包含修剪算法通过将导致更有效的实现的这个单个GITE操作员一致地被定义。而且,我们提供他们的正确性证明。这个工作能被看作使ROBBD算法适应抽象种类和uninterpreted功能的领域的一个方法。新工具,叫的NuMDG,接受一种扩大SMV语言,支持抽象数据排序。最后,我们表明NuMDG工具的效率并且从SMV用一套基准评估它的表演的现在的试验性的结果包装。

  • 简介:非编码的RNA的许多班(ncRNAs;包括YRNA,跳过RNA,RNasePRNA,和MRPRNA,以及一个新奇的类最近在Dictyostelium发现了discoideum)能被被糟糕保存的区域分开的短却保存得好的顺序元素的一个模式描绘有时高度可变的长度。象强风那样的本地排列算法为在genomic序列的如此的ncRNAs的新相当或相同的事物的发现因此是不合适的。Fragrep工具相反为检测在一个给定的命令发生的模式碎片实现一个有效算法。为每模式碎片,干涉序列的长度上的失配忍耐和界限能独立被指定。而且,匹配能被一个统计上激发得好的得分计划评价。
