Web(1)The worst case time complexity of k-SAT with n variables and m clauses reaches the maximum value, if m is Cn where C is a constant. (2)The exponential time hypothesis. This question comes from a view about input size of problems. For example, an instance of 3-SAT with n variables is a 3CNF formula and the length of the formula could be O(n^3). 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 ...
