WebThe generalized cost-scaling method, introduced in [4, 7], is theoretically superior to other methods ... [3, 7, 10], multiple scaling algorithms [1], and cycle-canceling algorithms [6]. We restrict our study only to push-relabel variant of the cost- scaling approach. This variant is the most promising since, in the context of the closely related Webalgorithm is used for graph connectivity not because it is a good algorithm, but because it fits within the “think like a vertex” computational model [15], whose imple-mentations scale well. Unfortunately, in this case (and many others) the appealing scaling properties are largely due to the algorithm’s sub-optimality; label propagation
