终端对可靠性问题,即确定存在至少一条连接终端节点的工作边路径的概率的问题,已知是NP难的。因此,边界算法用于科普大的图形尺寸。然而,它们在内存方面仍然有巨大的需求。我们提出了一个内存效率的实现Gobien-Dotson边界算法的扩展。在不增加运行时间的情况下,相关数据结构的压缩允许我们使用低带宽高容量存储。这样,可用的硬盘空间就成为限制因素。根据输入结构,可以处理具有数百条边的图(即系统组件)。
The terminal-pair reliability problem, i.e. the problem of determining the probability that there exists at least one path of working edges connecting the terminal nodes, is known to be NP-hard. Thus, bounding algorithms are used to cope with large graph sizes. However, they still have huge demands in terms of memory. We propose a memory-efficient implementation of an extension of the Gobien-Dotson bounding algorithm. Without increasing runtime, compression of relevant data structures allows us to use low-bandwidth high-capacity storage. In this way, available hard disk space becomes the limiting factor. Depending on the input structures, graphs with several hundreds of edges (i.e. system components) can be handled.
