(a) Use the recursion tree method to guess tight 5 asymptotic bounds for the recurrence T(n)-4T(n/2)+n. Use substitution method to prove it.
Consider the recurrence T (n) = 3 · T (n/2) + n. • Use the recursion tree method to guess an asymptotic upper bound for T(n). Show your work. • Prove the correctness of your guess by induction. Assume that values of n are powers of 2.
Draw the recursive tree and justify for the upper bound sum. 1. (20 points) Let if n=1 T(n) = 4T(n/2) + nº log(n) otherwise Use the recursion tree method, show that T(n) = O(né logº (n)). You can assume that n is a power of 2. We expect the drawing of the recursion tree to derive a summation, and a rigorous justification of the upper bound of the sum.

Use a recursive tree method for recurrence function T(n)= 2T(n/5)+3n. then use substitution method to verify your answer
Suppose the following is a divide-and-conquer algorithm for some problem. "Make the input of size n into 3 subproblems of sizes n/2 , n/4 , n/8 , respectively with O(n) time; Recursively call on these subproblems; and then combine the results in O(n) time. The recursive call returns when the problems become of size 1 and the time in this case is constant." (a) Let T(n) denote the worst-case running time of this approach on the problem of size n....

(15 pts) 1. Create the recursion tree for the recurrence T(n)-T(2n/5)T3n/5) O(n). Show total complexity
3. Determine the asymptotic complexity of the function defined by the recurrence relation. Justify your solution using expansion/substitution and upper and/or lower bounds, when necessary. You may not use the Master Theorem as justification of your answer. Simplify and express your answer as O(n*) or O(nk log2 n) whenever possible. If the algorithm is exponential just give exponential lower bounds c) T(n) T(n-4) cn, T(0) c' d) T(n) 3T(n/3) c, T() c' e) T(n) T(n-1)T(n-4)clog2n, T(0) c' 3. Determine the...
