Detecting Backdoor Sets with Respect to Horn and Binary Clauses
We study the parameterized complexity of detecting backdoor sets for instances of the propositional satisfiability problem (SAT) with respect to the polynomially solvable classes ...

Computing Horn Strong Backdoor Sets Thanks to Local Search
In this paper a new approach for computing Strong Backdoor sets of boolean formula in conjunctive normal form (CNF) is proposed. It makes an original use of local search technique...

Tradeoffs in the Complexity of Backdoor Detection
Abstract There has been considerable interest in the identification of structural properties of combinatorial problems that lead to efficient algorithms for solving them. Some of...
