PMS WebReplay the introductory video explaining DPLL and (at 30:00) Two-Watched Literals.. The most naive way to solve SAT is to guess the value of all variables, one by one. This is however too inefficient: after guessing, for example, that some variable X is false, there are typically several variables Y whose value is forced by the clauses. This is the main idea …

Only when this pre-check fails, i.e. when one of the watched literals is affected, we need to perform any work. Otherwise the cost is not even constant per unaffected constraint, there is in fact no work to do for them at all. 8d用英语怎么说WebThe idea of the Two-watched literals is to keep 2 literals for every clause that are not instantiated.
