Abstract: We present an efficient algorithm for simulating percolation transitions of mutually supporting viable clusters on multiplex networks (also known as “catastrophic cascades on interdependent networks”). This algorithm maps the problem onto a solid-on-solid-type model. We use this algorithm to study interdependent agents on duplex Erdös-Rényi (ER) networks and on lattices with dimensions 2, 3, 4, and 5. We obtain surprising results in all these cases, and we correct statements in the literature for ER networks and for two-dimensional lattices. In particular, we find that d=4 is the upper critical dimension and that the percolation transition is continuous for d≤4 but—at least for d≠3—not in the universality class of ordinary percolation. For ER networks we verify that the cluster statistics is exactly described by mean-field theory but find evidence that the cascade process is not. For d=5 we find a first-order transition as for ER networks, but we find also that small clusters have a nontrivial mass distribution that scales at the transition point. Finally, for d=2 with intermediate-range dependency links we propose a scenario that differs from that proposed in W. Li et al. [Phys. Rev. Lett. 108, 228702 (2012)].
