#### Thanks for the Fuzzy Memories

In the 1990's Manindra Agrawal and V. Arvind published a paper claiming that if SAT is reducible to a (non-uniform) weighted threshold function then P = NP. Their...

#### Two Recent Complexity Books omit Mahaney's theorem- ovesight or wisdom?

In a prior post (a while back) I pondered if Mahaney's theorem (SAT \le_m S, S Spare, implies P=NP) should be taught in a basic grad course in complexity. I thought...
