The result uses a gadget-style reduction from the general Max k CSP problem, Webcomplexity of k-SAT increases with increasing k.Define s k (for 3) to be the infimum of f : there exists an O (2 n) algorithm for solving k-SAT g. Define ETH (Exponential-Time Hypothesis) for k-SAT as follows: for k 3, s k > 0. In other words, for , k-SAT does not have a subexponential-time algorithm. In this paper, we show that s k is an ...
WebWe give hundreds of new exact Rado number values and describe a SAT-based method to produce formulas for three infinite families of three-color Rado numbers. If time permits, we will also discuss the connections between Ramsey theory and complexity of Nullstellensatz certification. We show that a broad class of “Ramsey-type” problems have ...

An inapproximability factor of 6=5 " was shown for 1-in-E3SAT in [6]. We are unaware of any comprehensive prior investigation into the complexity of approximating 1-in-kSAT and its variants for larger k.
