“…Therefore, the two-terminal reliability index in this work, denoted by R (d,T,b) , is defined as the probability of transmitting d units of data from a source to a destination through a single path in the network within T units of time and budget b. Many algorithms have been proposed in the literature to compute the network reliability with or without the time and budget constraints which are usually based on the minimal cuts [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24] or minimal paths [4], [8], [9], [10], [25], [26], [27], [28], [29], [30], [31], [32], [33], [34], [35], [36]. Although many studies have been made so far in this regard, the problem of assessing the reliability of communication networks is a well-known NP-hard combinatorial problem [37], and hence the research continues.…”
