Tautologies - PowerPoint PPT Presentation


Propositional Proof Complexity and Lower Bounds

Studies focus on the intractability of propositional proof complexity, exploring the power of proof systems to verify tautologies. Discussion on known lower bounds and challenges in proving hardness of certain tautologies.
