https://logictools.org/prop.htmlSolving 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.Read from here about the differences between algorithms.

In this hand-out I treat the notation of truth-functional propositional logic and first-order predicate logic as a language, and give guidance on translating from English into this foreign language.
