Propositional 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 “You liked it” or “You should have put a ring on it.”

Chapter 5 - Propositional Resolution - Stanford Logic Group
logic.stanford.edu/intrologic/notes/chapter_05.html
Propositional Resolutionis a powerful rule of inference for Propositional Logic. Using Propositional Resolution (without axiom schemata or other rules of inference), it is possible to build a theorem prover that is sound and complete for all of Propositional Logic.
Resolution Theorem Proving: Propositional Logic
ocw.mit.edu › courses › electrical-engineering-and
Propositional Logic • Propositional resolution • Propositional theorem proving •Unification Today we’re going to talk about resolution, which is a proof strategy. First, we’ll look at it in the propositional case, then in the first-order case. It will actually take two lectures to get all the way through this.

Solving 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.
