“…The permutation π = (5, 2, 3, 1, 6, 4) and its critical path u * = (2, 5, 5) which generate three blocks: B 1 = (5, 2), B 2 = (2, 3, 1, 6) and B 3 = (6, 4), and three relevant internal blocks B * 2) Block Properties: Block properties (BPs) are some general properties associated with the graph representation of scheduling problems with the makespane criterion [12]. This section introduce two BPs proposed by Nowicki [11] and Grabowski [13] [14] that are associated with the neighbourhood structure.…”
