Explore the complexity of the permanent problem in this graduate-level lecture on Computational Complexity Theory. Delve into the proof that the permanent is #P-complete, covering topics such as cycle covers, weight reductions, the NAND graph, and Sharp 3SAT. Learn about clause gadgets, consistency checks, and hole reductions as part of the main reduction strategy. Analyze the intricacies of weak identification and edge pair identification in this advanced exploration of computational complexity concepts.
