Improved Bound for the PPSZ/Schöning-Algorithm for 3-SAT
The PPSZ Algorithm presented by Paturi, Pudlak, Saks, and Zane in 1998 has the nice feature that the only satisfying solution of a uniquely satisfiable 3-SAT formula can be found in expected running time at most O(1.3071n). Its bound degenerates when the number of solutions increases. In 1999, Schöning proved an O(1.3334n) bound for 3-SAT. In 2003, Iwama and Tamaki combined both algorithms to y...

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
15 صفحه اولAn Improved Upper Bound for SAT
We give a randomized algorithm for testing satisfiability of Boolean formulas in conjunctive normal form with no restriction on clause length. Its running time is at most 2n(1−1/α) up to a polynomial factor, where α = ln(m/n) + O(ln lnm) and n, m are respectively the number of variables and the number of clauses in the input formula. This bound is asymptotically better than the previously best ...

We slightly improve the pruning technique presented in Dantsin et. al. (2002) to obtain an O∗ (1.473n) algorithm for 3-SAT.
متن کاملA Probabilistic 3-SAT Algorithm Further Improved
In [?], Schöning proposed a simple yet efficient randomized algorithm for solving the kSAT problem. In the case of 3-SAT, the algorithm has an expected running time of poly(n) · (4/3) = O(1.3334) when given a formula F on n variables. This was the up to now best running time known for an algorithm solving 3-SAT. In this paper, we describe an algorithm which improves upon this time bound by comb...
