Abstract

Zhu et al. [Theoret. Comput. Sci. 758 (2019) 1--8] introduced the hh-edge tolerable diagnosability to measure the fault diagnosis capability of a multiprocessor system with faulty links. This kind of diagnosability is a generalization of the concept of traditional diagnosability. A graph is called a maximally connected graph if its minimum degree equals its vertex connectivity. It is well-known that many irregular networks are maximally connected graphs and the hh-edge tolerable diagnosabilities of these networks are unknown, which is our motivation for research. In this paper, we obtain the lower bound of the hh-edge tolerable diagnosability of a tt-connected graph and establish the hh-edge tolerable diagnosability of a maximally connected graph under the PMC model and the MM^* model, which extends some results in [IEEE Trans. Comput. 23 (1974) 86--88], [IEEE Trans. Comput. 53 (2004) 1582--1590] and [Theoret. Comput. Sci. 796 (2019) 147--153].
