Through re-executing SCED based on a large amount of historical operation data, system operators first classify the four different cases due to a targeted attack line error, which are illustrated in Sect.
C&W, following the conventional wisdom of the time, piled into the long-haul data-networking business, backing away from its local-phone operations in Britain and its former colonies (hangovers from C&W's historical roots as operator of the British empire's communications network).

One may refer for the historical development of fractional operators to [5, 6].
It is challenge work to design parareal algorithms for time-fractional differential equations due to the historical effect of the fractional operator.
The aim of this paper is to present some historical roots of the diagonal operators, to study the fixed points of this class of operators, and to give some applications.
2. Historical roots of the diagonal operators.
Furthermore, a purposeful detection operator based on some historical information is proposed to help the population to jump out of local optima.
In this paper, we introduce the notion of diagonal operator, we present the historical roots of diagonal operators and we give some fixed point theorems for this class of operators.
