https://logictools.org/prop.htmlWhile resolution has been the basis of most state-of-art predicate logic solvers, for propositional logic it is inferior to the DPLL method described next. DPLL (Davis-Putnam-Logemann-Loveland) searchis essentially a constraint solver based on the combination of …

logictools.org › propSolving a classical propositional formula means looking for such values of variables that the formula becomes true. For example, (a -> b) & a becomes true if and only if both a and b are assigned true. You can select and try out several solver algorithms: the "DPLL better" is the best solver amongst the options.

web.stanford.edu › class › archivePropositional Logic Propositional logic is a mathematical system for reasoning about propositions and how they relate to one another. Every statement in propositional logic consists of propositional variables combined via propositional connectives. Each variable represents some proposition, such as
