Pseudorandom Self-Reductions for NP-Complete Problems
summary
Claim: non-adaptive pseudorandom self-reduction for Max Clique (and every nontrivial hereditary max-subgraph problem) holds assuming the non-uniform planted clique conjecture. The reduction fixes a random set S of size n^ε, preserves edges inside S from the input and randomizes others, so a K-clique maps to roughly K / n^{1-ε} (with at most +3 log n noise) and the outputs are indistinguishable from uniform via an XOR-style argument; a distinguisher would violate the planted-clique hardness.
