Polluted Bootstrap Percolation

Bootstrap percolation is a fundamental cellular automaton model for nucleation. Despite its simplicity, the model holds many surprises. I’ll focus on how growth from sparse random seeds is affected by sparse random impurities in the medium. The answer involves using recent oriented surface technology to construct a stegosaurus. Based on joint work with Janko Gravner and David Sivakoff.
