Lecture 18

Today we covered: Hardness vs. randomness corollaries of Nisan-Wigderson; Impagliazzo-Wigderson Theorem (fE requiring circuits of size 2εn implies P=BPP); Hardness Amplification , 1-1/poly(n) hardness to 1/2+1/poly(n) hardness, with the XOR Lemma; Impagliazzo's proof via the Hard-Core Set Theorem (with Nisan's proof via the Minimax Theorem).
