The stomach plays a crucial role in digestion and is divided into four regions - cardia, fundus, body, and pyloric part. Understanding the anatomy of the stomach is essential for surgical interventions, including treatment for benign and malignant gastric diseases like peptic ulcer disease. Surgical

Today's lecture delved into NP-completeness, focusing on the Cook-Levin Theorem and the Clique Problem. NP-completeness is defined as a language that is in NP and all other languages in NP are polynomial-time reducible to it. The Cook-Levin Theorem states that SAT, a Boolean satisfiability problem,
