Abstract
We prove that the one-dimensional sandpile prediction problem is in LOGDCFL, a subset of AC1. The previously best known upper bound on the ACi-scale was AC2. Furthermore, we prove that the one-dimensional sandpile prediction problem is hard for TC0 and thus not in AC1-ε for any constant ε > 0.
