Oracles Are Subtle But Not Malicious Scott Aaronson (no affiliation)

2
Are you frustrated by the scarcity of nonrelativizing circuit lower bounds? Dissatisfied by results that apply only to made-up classes like MA EXP ? Do you hunger for an oracle relative to which PP has linear-size circuits? Or … do you feel like its easy to construct a relativized world where anything is truelike you never get more out of oracle results than you put in to them?

3
If you answered yes to any of these questions, take a look at ECCC TR05-040. Oracle where PP has linear-size circuits Our competitors can only promise this for MA and P NP Oracle where P NP = P = PEXP New proof that in the unrelativized world, PP does NOT have linear-size circuits Bonus! PP doesnt have linear-size quantum circuits either Extra Bonus: Not even quantum circuits with quantum advice What are you waiting for?? DOWNLOAD NOW! Web servers are standing by

4
Oracle where has linear-size circuits If P=NP, then given any Boolean function f with polynomial-size circuits, you can learn such a circuit in The implications are endless: computational learning theory (Bshouty et al.s algorithm), circuit minimization, Karp-Lipton collapses…
