The progressive advanced method for solving recursive equations -- the Generation Method

assume that the approximate upper bound of the solution isO(N). We will try to prove the proper number for the appropriate choiceCAnd Natural NumberN0, whenN≥NWhen 0T(N) ≤CN. Place Our speculation into the recursive equation and get: We cannot infer from thisT(N) ≤CNThe induction method has encountered obstacles. The reason is that the right-end ratio of (6.8)CNAn extra low-level constant. To offset this low order, we can subtract a undetermined low order from the original conjecture.BThat
