How do you solve a recurrence problem?
1) Substitution Method: We make a guess for the solution and then we use mathematical induction to prove the guess is correct or incorrect. 2) Recurrence Tree Method: In this method, we draw a recurrence tree and calculate the time taken by every level of tree. Finally, we sum the work done at all levels.
How is master method used to solve recurrence relations?
The master method is a formula for solving recurrence relations of the form: T(n) = aT(n/b) + f(n), where, n = size of input a = number of subproblems in the recursion n/b = size of each subproblem.
Which of the following is used to solve recurrence?
Explanation: Master’s theorem is a direct method for solving recurrences.
Can a recurrence of the form T(N) be solved using master theorem?
1) It is not necessary that a recurrence of the form T (n) = aT (n/b) + f (n) can be solved using Master Theorem. The given three cases have some gaps between them. For example, the recurrence T (n) = 2T (n/2) + n/Logn cannot be solved using master method. Practice Problems and Solutions on Master Theorem.
How to calculate the total work done in a recurrence tree?
If we draw recurrence tree of T(n) = aT(n/b) + f(n), we can see that the work done at root is f(n) and work done at all leaves is Θ(n c) where c is Log ba. In recurrence tree method, we calculate total work done.
What is the difference between master method and recurrence tree method?
Master method is mainly derived from recurrence tree method. If we draw recurrence tree of T (n) = aT (n/b) + f (n), we can see that the work done at root is f (n) and work done at all leaves is Θ (n c) where c is Log b a. And the height of recurrence tree is Log b n In recurrence tree method,…
