Np hard code generation problem
Web7 okt. 2024 · You've now shown sorting is at least as hard as finding the maximum number, or analogously, that finding the optimal decision tree is as hard as problem A. In the paper you linked, problem A goes by the name "exact cover by 3-sets". Then, you might ask how complexity theorists proved EC3 or any of the NP-hard problems are actually intractable.
