Fibonacci Search Visualizer using PyQt5
In this article we will see how we can make a PyQt5 application which will visualize the exponential search algorithm.
Fibonacci search technique is a method of searching a sorted array using a divide and conquer algorithm that narrows down possible locations with the aid of Fibonacci numbers. Compared to binary search where the sorted array is divided into two equal-sized parts, one of which is examined further, Fibonacci search divides the array into two parts that have sizes that are consecutive Fibonacci numbers.
GUI implementation steps :
1. Create a list of label according to the given list of numbers
2. Set their text, border, color and geometry with respective gap from each other
3. Each label height should be proportional to the value of each number
4. Create a start and pause push button to start the searching and pause the searching
5. Create a result label to show the searching status
Back end implementation steps :
1. Create label list corresponding to the given numbers
2. Create variable for the index used by Fibonacci search and flag for searching and flag for searching minimum Fibonacci number and for searching value after getting the Fibonacci number
3. Add action to the push button their action should change the flag status i.e start action should make flag true and pause action should make flag false
4. Create timer object which calls a method after every specific time
5. Inside the timer method check for the flag is flag is true begin the search of Fibonacci number
6. After finding the fibonacci number find the given number within the range
7. Show the result
Below is the implementation
