Recognizability & Long Cycles in USOs

In this talk, the following problem is considered: Given a Boolean Circuit with n inputs and n outputs, decide if it represents a Unique Sink Orientation (USO). We prove this problem to be coNP-complete. However, the situation is more involved for Acyclic USOs (AUSO). While it remains coNP-hard to recognize an AUSO, we leave open the problem of inclusion that there exist cyclic USOs with superpolynomially long cycles.
