Automated reasoning

Definition

Automated reasoning refers to the use of algorithms and computer software to derive conclusions from premises or to solve logical problems without human intervention. It plays a crucial role in various fields such as artificial intelligence, formal verification, and theorem proving. This process is closely linked to proof normalization and cut elimination, as both methods aim to simplify and streamline logical proofs, making them more accessible for computational analysis.
