Model elimination

Model elimination is a strategy used in automated theorem proving, particularly within the context of first-order logic. It is a refutation-based approach that aims to establish the unsatisfiability of a set of clauses, thus proving the validity of a given statement. The key components of model elimination are: 1. **Refutation**: The objective is to show that a contradiction can be derived from a set of premises and a negation of the statement to be proved.
