Therefore,it is valuable to identify whether the system is conditionally t-diagnosable or t-diagnosable and derive the corresponding conditional diagnosability and diagnosability. In the paper,distinguishable measures of pairs of distinct faulty sets with a new perspective on establishing functions are focused.Applying distinguishable function and decision function,it is determined whether a system is conditionally t-diagnosable( or t-diagnosable) or not under the PMC( Preparata,Metze,and Chien)model directly. Based on the decision function,a novel conditional diagnosability algorithm under the PMC model is introduced which can calculate conditional diagnosability rapidly.展开更多

Hsu [Appl. Math. Comput., 2012, 218（21）： 10406-10412] proposed a new measure for fault diagnosis of the system, which is called the 9-good-neighbor conditional diagnosability that restrains every fault-free node containing at least 9 fault-free neighbors. As a famous topological structure of intereonnection networks, the n-dimensional star graph Sn has many good properties. In this paper, we establish the 9_good-neighbor conditional diagnosability of Sn under the PMC model and MM＊ model.展开更多
