This paper introduces a computational model called a fold-and-cut
machine which allows as operations simple folds and unfolds, straight-line
cuts, and inspection for a through-hole (hole through all the layers of
paper). We show that a (deterministic) fold-and-cut machine can decide a 3SAT
instance with n variables and m clauses using
O(n m + m2) operations
(with just one cut and inspection), showing that the machine is at least as
powerful as a nondeterministic Turing machine.
