Boolean satisfiability
WebJun 8, 2024 · 2-SAT. SAT (Boolean satisfiability problem) is the problem of assigning Boolean values to variables to satisfy a given Boolean formula. The Boolean formula will usually be given in CNF (conjunctive normal form), which is a conjunction of multiple clauses, where each clause is a disjunction of literals (variables or negation of variables). … WebThe author describes the Boolean satisfiability method for generating test patterns for single stuck-at faults in combinational circuits. This new method generates test patterns in two steps: first, it constructs a formula expressing the Boolean difference between the unfaulted and faulted circuits, and second, it applies a Boolean satisfiability algorithm …

WebMar 2, 2024 · This paper reviews the recent literature on solving the Boolean satisfiability problem (SAT), an archetypal NP-complete problem, with the help of machine learning techniques. Despite the great success of modern SAT solvers to solve large industrial instances, the design of handcrafted heuristics is time-consuming and empirical. Under … WebFeb 12, 2024 · We then train Graph Neural Networks, or GNNs, to classify problem instances as satisfiable or unsatisfiable (Scarselli et al., 2009b). Our results are intriguing. GNNs are capable of classifying satisfiability. We are still in the process of exploring how formal problem difficulty affects graph representations of CNF formulas, and how exactly ...
