Infeasibility of Instance Compression and Succinct PCPs for NP
The OR-SAT problem asks, given Boolean formulae φ1, . . . , φm each of size at most n, whether at least one of the φi’s is satisfiable. We show that there is no reduction fr...

On Bounded Truth-Table, Conjunctive, and Randomized Reductions to Sparse Sets
In this paper we study the consequences of the existence of sparse hard sets for NP and other complexity classes under certain types of deterministic, randomized, and nondetermini...

Solving minones-2-sat as Fast as vertex cover
The problem of finding a satisfying assignment for a 2-SAT formula that minimizes the number of variables that are set to 1 (min ones 2–sat) is NP-complete. It generalizes the w...

Satisfiability of Acyclic and Almost Acyclic CNF Formulas
We study the propositional satisfiability problem (SAT) on classes of CNF formulas (formulas in Conjunctive Normal Form) that obey certain structural restrictions in terms of thei...

Exploiting Symmetries to Speed Up SAT-Based Boolean Matching for Logic Synthesis of FPGAs
Boolean matching is one of the enabling techniques for technology mapping and logic resynthesis of Field Programmable Gate Array (FPGA). SAT-based Boolean matching (SAT-BM) has bee...
