The Computational Complexity of One-Dimensional Sandpiles
Abstract. We prove that the one-dimensional sandpile prediction problem is in AC1 . The previously best known upper bound on the ACi -scale was AC2 . We also prove that it is not i...

Computational Complexity of Avalanches in the Kadanoff two-dimensional Sandpile Model
In this paper we prove that the avalanche problem for the Kadanoff sandpile model (KSPM) is P-complete for two-dimensions. Our proof is based on a reduction from the monotone circ...

The Complexity of Three-Dimensional Critical Avalanches
In this work we study the complexity of the three-dimensional sandpile avalanches triggered by the addition of two critical configurations. We prove that the algorithmic problem c...
