Do you not understand that an O(n^100) algorithm is in P, but can never be run feasibly on a computer for any non trivial amounts of n? For n=10 you are already

Do you not understand that an O(n^100) algorithm is in P, but can never be run feasibly on a computer for any non trivial amounts of n? For n=10 you are already far beyond the number of Atoms in the universe. I don't think you have any clue what you are actually talking about.
