Abstract
The BFW model introduced by Bohman, Frieze, and Wormald Random
Struct. Algorithms 25, 432 (2004), and recently investigated in the
framework of discontinuous percolation by Chen and D'Souza Phys. Rev.
Lett. 106, 115701 (2011), is studied on the square and simple-cubic
lattices. In two and three dimensions, we find numerical evidence for a
strongly discontinuous transition. In two dimensions, the clusters at
the threshold are compact with a fractal surface of fractal dimension d(f) = 1.49 +/- 0.02. On the simple-cubic lattice, distinct jumps in the
size of the largest cluster are observed. We proceed to analyze the
tree-like version of the model, where only merging bonds are sampled,
for dimension two to seven. The transition is again discontinuous in any
considered dimension. Finally, the dependence of the cluster-size
distribution at the threshold on the spatial dimension is also
investigated.
