More on BPP and the polynomial-time hierarchy

Research output: Contribution to journalArticlepeer-review


We simplify known proofs that BPP lies within the Polynomial-time Hierarchy. Furthermore, our simple proof shows that BPP is contained in a complexity class that presumably lies even lower in this Hierarchy than was previously known. Our technique also simplifies the proof that one-sided-error IP equals two-sided-error IP.
