On the power of two-point based sampling

TLDR
A new sampling technique is presented that consists of picking two elements at random, and deterministically generating a long sequence of pairwise-independent elements that is guaranteed to intersect, with high probability, any set of non-negligible density.

Probabilistic checking of proofs: a new characterization of NP

TL;DR: It is shown that approximating Clique and Independent Set, even in a very weak sense, is NP-hard, and the class NP contains exactly those languages for which membership proofs can be verified probabilistically in polynomial time.

P = BPP if E requires exponential circuits: derandomizing the XOR lemma

TL;DR: A pseudo-random generator which produces n instances of a problem for which the analog of the XOR lemma holds is given, and it is shown that if any problem in E = DTIAl E(2°t”j) has circuit complexity 2Q(”), then P = BPP.

Simple Constructions of Almost k-wise Independent Random Variables

TL;DR: This work presents three alternative simple constructions of small probability spaces on n bits for which any k bits are almost independent and their simplicity is their simplicity.
