ABSTRACT
In a simple graph , let
be the minimum cardinality of the neighbourhoods of any two adjacent vertices, i.e.
. Let
be the connectivity of G. In this paper, we prove that the pessimistic diagnosability of G, denoted by
, is equal to
if the following two conditions hold: (1) for any subset
with
,
; (2)
. As examples of its applications, we prove that the pessimistic diagnosabilities of n-dimensional hypercube-like network
, dual-cube
, pancake network
, and burnt pancake graph
are
(
),
(
),
(
) and
(
), respectively.
