Expert Solution & Answer
Chapter 9.6, Problem 9.12CP
Explanation of Solution
Basic operations:
The basic operation is the initial step in the
- Normally, the algorithm executes the basic step in constant time rather than considering about the size of the input.
- So, it means that size of the bound does not affect the efficiency of the operations.
- The complexity of an algorithm can be found out by finding the number of basic steps required for an input.
Comparing the efficiency of an algorithm:
In the given question, one algorithm requires “

Two algorithms A, B sort the same problem. When you go through each algorithm and break them down into their primitive operations, each can be represented as below
A = n4 + 100n2 + 10n + 50
B = 10n3 + 2n2 + nlogn + 200

- A computer science student designed two candidate algorithms for a problem while working on his part-time job The time complexity of these two algorithms are T,(n) = 3 n logn and T2(n) = n6/5 a) Which algorithm is better? Why? b) If we run both algorithms at the same time with an input size of 105, which algorithm produces results faster than the other one? Why?arrow_forwardSuppose that the running time of an algorithm A is T(n) = n2. If the time it takes for algorithm A to finish on an input of size n 10 is 100ms, what will be the time that it will take for A to finish on an input of size 20? Assume that the algorithm runs on the same machine.arrow_forwardSuppose you have algorithms with five running times. Assume these are the exact running times. How much slower do each of these algorithms get when you (a) double the input or (b) increase the input size by one? Do both. This problem requires discrete math. I solved all of these but I had a quick question. My teacher wanted us to use the big 0 notation for these running times, but the problem is that I'm not sure if that's necessary for these problems for the question it's asking. I tried to the big 0 notations for the first three. For (a) I got 8n3. Which I'm not sure is right. For example, for 1b I got 3n2 + 3n + 1 for how much slower these get from the original. Is that correct? Was I supposed to do something more for the big 0 notation. You can check to see if these answers are correct. The big O notation formula is f(n) = 0(g(n)). (a) n2 For double size I got 4n2. I got 2n + 1 from the input the size by one. I think that's all I need to do. I got similar answers for theother…arrow_forward
