Marek Fuchs,Siegfried Lamnek,Nina Baurons. The recursion trees of DPLL algorithm executions on unsatisfiable formulas are equivalent to tree-like resolution proofs. Therefore, lower bounds for tree-like resolution (known since 1960s) apply to them. However, these lower bounds say nothing about their behavior on . formulas. Proving expon

The only known complexity bound for this problem is a doubly-exponential upper bound. We establish a singly-exponential upper bound and show that there exi
