Empirical Performance of Internal Sorting Algorithm

Faki Ageebee Silas, Yusuf Musa & S. Akosu Joyce · Journal of Advances in Mathematics and Computer Science · 2016

Internal Sorting Algorithms are used when the list of records is small enough to be maintained entirely in primary memory for the duration of the sort, while External Sorting Algorithms are used when the list of records is large enough to be maintained in physical memory hence a...

An ROBDD Algorithm for the Reliability of Double-Threshold Systems

Ali Muhammad Ali Rushdi & Hasan Ahmed Bjaili · Journal of Advances in Mathematics and Computer Science · 2016

A double-threshold system (DTS) is a system that is successful if and only if the weighted arithmetic sum of its successes/failures equals or exceeds a certain threshold T1 and is smaller than or equal to a certain threshold T2. Generally a DTS is neither symmetric nor coherent....
