A -diagnosable system refers to such a system that all the faulty nodes of the system can be isolated within a set of size at most s in the presence of at most t faulty nodes. Moreover, it increases the allowed faulty nodes, hence enhancing the diagnosability of the system. We can find that the -diagnosability of n-dimensional folded hypercube has not been studied under the PMC model and MM* model. In this paper, we determine the -diagnosability of under the PMC model and MM* model. First, we propose some new fault tolerant properties of . Then we prove that the -diagnosability of n-dimensional folded hypercube is for where under both the PMC model and MM* model. In addition, we establish two -diagnosis algorithms of complexity and complexity to isolate the faulty nodes in a node subset of the system under the PMC model and MM* model, respectively. The comparison analysis results showed that the -diagnosability of is the largest, and it increases faster than the other types of diagnosability as n increases.

一种 -可诊断系统是指在最多存在t个故障节点的情况下,可以在最多s个大小的集合内隔离系统所有故障节点的系统。此外,它增加了允许的故障节点,从而增强了系统的可诊断性。我们可以发现,-n维折叠超立方体的可诊断性尚未在 PMC 模型和 MM* 模型下进行研究。在本文中,我们确定- 可诊断性 在 PMC 模型和 MM* 模型下。首先,我们提出了一些新的容错特性. 然后我们证明-n维折叠超立方体的可诊断性 是 为了 在哪里 在 PMC 模型和 MM* 模型下。此外,我们建立了两个- 复杂度诊断算法 和复杂性 分别在PMC模型和MM*模型下隔离系统节点子集中的故障节点。对比分析结果表明,- 可诊断性 是最大的,并且随着n 的增加,它比其他类型的可诊断性增加得更快。
