Poly time reduction property

WebThe Lenstra–Lenstra–Lovász (LLL) lattice basis reduction algorithm is a polynomial time lattice reduction algorithm invented by Arjen Lenstra, Hendrik Lenstra and László Lovász in 1982. [1] Given a basis with n -dimensional integer coordinates, for a lattice L (a discrete subgroup of Rn) with , the LLL algorithm calculates an LLL ... Webp Li.e L0is polynomial-time Karp-reducible to L. Note that, the poly-time reduction in the de nition can also be replaced with implicit logspace reduction, in that case we would be considering the question whether BPP = L. Thus, we would like to come up with a language L2BPP, such that for every other language L02BPP,

WebA Formula Simulating the Tableau We construct a Boolean CNF formula φw that “mimics” the tableau. Given the string w, it takes O(n2c) steps to construct φw. The following property holds: φw ∈ SAT iff M accepts w. So the mapping w → φw is a poly time reduction from L to SAT, establishing L ≤P SAT.
