hi all there seems to be a deep/not-much-explored phenomenon in the way that SAT resolution proofs can define a tree and/or a DAG & its relationship to lower bounds/circuit complexity. could there ...
2-SAT is in P. Additionally, a (CNF) SAT-problem is trivially poly-time solvable if no two expressions can be resolved (via Robinson resolution, ie for every pair of disjunctive clauses, they either ...
I'm searching for an authoritative definition of resolution (logic resolution). Preferably on a reference freely available on the Internet (so I can read it right now). If this is too broad then ...
(I posted this question on MathSE first, no answer, that is the reason why I come here.) Let $F$ be a 3-CNF formula on $n$ variables. A clause $c$ is implied by the formula if $F$ and $F \wedge c$ ...
The question looks very simple, that is why I posted it first on MathSE, unsuccesfully - no answer for 12 days. I tried to find a short and elegant answer to the question, but I haven't succeed yet. ...
This question is about propositional logic and all occurrences of "resolution" should be read as "propositional resolution". This question is something extremely basic but it has been bothering me ...
