The authors suggest that, for some reasoning tasks, searching for such an assignment with a method like GSAT could be more practical than proving a result. If this holds, it would encourage people to recast certain problems as satisfiability searches instead of using traditional proof methods.","findings":["GSAT solved hard, randomly generated satisfiability problems an order of magnitude larger than those traditional methods such as Davis-Putnam or resolution can handle.","GSAT also solved structured satisfiability problems quickly, including encodings of graph colouring, N-queens and Boolean induction.","The authors view GSAT as best seen as a model-finding procedure and discuss general application strategies and limitations."],"terms":[{"term":"theorem-proving","means":"Showing by logical steps that a conclusion must follow from a set of given statements."},{"term":"model-finding","means":"Searching for an assignment of values that makes a set of logical statements all true."},{"term":"reformulate","means":"To restate a problem in a different form so that it can be tackled with a different method."}],"basis":"abstract","abstractFrom":"openalex","model":"claude-sonnet-5-5","writtenAt":"2026-10-22T01:30:37.057Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-22T01:30:37.057Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
