Algorithms and Basic Data Structures
This part involves writing and testing code. You are to make an experiment with 3 sorting algorithms partially given on Blackboard: Insertion sort, Mergesort, Quicksort. First, create a positive integer array of 10000 (ten thousand) elements with random values in it. Then, run the algorithms on this array by recording their running times. That is, take note of the time just before the sorting starts, and just after the sorting finishes, and record the difference. For a complete experiment, do the following:
Perform the experiment on arrays of size 10000, 20000, 40000, 80000, 160000, 320000, where you select the pivot in Quicksort randomly. Record all the running times and plot them using a graph (for example with Excel). Interpret the results in a few sentences. How do you explain the success of Quicksort compared to Mergesort although both of them have the same asymptotic running time?
Again perform the experiment on sorted arrays (from the smallest to the largest) of size 10000, 20000, 40000, 80000, 160000, 320000, where you select the pivot in Quicksort as the first element of the part to be sorted. Record all the running times using a graph. Interpret the results in a few sentences.

Comparison of Sorting Algorithms You are required to implement all the sorting algorithms (Bubble, Selection, Insertion, Quick, Merge). Take help from lecture slides and welb . You will then create arrays of different sizes as instructed below, test each algorithm on each array and record the execution times of each individual algorithm on each array. . You will report these execution times in a table and then write a report explaining the execution times of the sorting algorithms according to...

This program should test the running time of these algorithms: Selection Sort Insertion Sort Bubble Sort Merge Sort Quick Sort Heap Sort You have access to the implementation of all of these sorting algorithms, and you may use what is provided in your text directly. Be sure to cite the source of these implementations in the header of your program. Please maintain the property that these sorting algorithms sort arrays in ascending order. For this homework, you will write a...

This part involves finding a new algorithm by yourself. You do NOT have to implement it with C++. You may just state the algorithm in pseudo-code. The problem is as follows: You have an integer array of n elements. You want to return true if there is a set of more than n/2 elements in the array with the same value, false otherwise. Notice that if the array is sorted (that is you are allowed to use a sorting algorithm),...

you will analyse two algorithms for finding the median of an array of integers. You will compare both algorithms in terms of timing, and hopefully design a hybrid algorithm that uses both, depending on input size. You will write a report describing your experiments and results. the following Java program implements two algorithms for finding the median of an array of integers. The first uses merge sort, and the other implements the recursive linear time selection algorithm, the task is...

Consider a variation of Merge sort called 4-way Merge sort. Instead of splitting the array into two parts like Merge sort, 4-way Merge sort splits the array into four parts. 4-way Merge divides the input array into fourths, calls itself for each fourth and then merges the four sorted fourths. a)Implement 4-way Merge sort from Problem 4 to sort an array/vector of integers and name it merge4. Implement the algorithm in the same language you used for the sorting algorithms...

Write a program that compares the execution speed of two different sorting algorithms: bubble sort and selection sort. It should do this via functions you must write with the following prototypes: void setRandomValues(int[], int[], int length); This function sets two integer arrays with identical random values. The first two arguments are two integer arrays of the same length, and the third argument is the length of those arrays. The function then sets each element in the first and second argument...

C++ Time the sequential search and the binary search methods several times each for randomly generated values, then record the results in a table. Do not time individual searches, but groups of them. For example, time 100 searches together or 1,000 searches together. Compare the running times of these two search methods that are obtained during the experiment. Regarding the efficiency of both search methods, what conclusion can be reached from this experiment? Both the table and your conclusions should...
