Planar SAT

Planar SAT (Satisfiability) is a particular case of the Boolean satisfiability problem (SAT) that involves deciding whether a given Boolean formula can be satisfied under the constraint that the variable or clause interactions can be represented in a planar graph. In general, the classic SAT problem asks whether there exists an assignment of truth values to Boolean variables such that a given formula is true. This can be represented as a graph where nodes represent variables and edges depict the relationships dictated by the clauses.
