What is Fibonacci heaps algorithm?

fibonacci heap is a heap


What is a heap?

Answer:- A sorting algorithm that works by first organizing the data to be sorted into a special type of binary tree called a heap. The heap itself has, by definition, the largest value at the top of the tree, so the heap sort algorithm must also reverse the order. It does this with the following steps:1. Remove the topmost item (the largest) and replace it with the rightmost leaf. The topmost item is stored in an array.2. Re-establish the heap.3. Repeat steps 1 and 2 until there are no more items left in the heap.The sorted elements are now stored in an array.A heap sort is especially efficient for data that is already stored in a binary tree. In most cases, however, the quick sort algorithm is more efficient.GOURAV KHARE (CHANDIGARH)gouravsonu89@gmail.com


What will be the difference in running time of the heap sort algorithm if you start to apply heap sort with an array elements rather than max heap elements?

The heap sort algorithm is as follows: 1. Call the build_max_heap() function. 2. Swap the first and last elements of the max heap. 3. Reduce the heap by one element (elements that follow the heap are in sorted order). 4. Call the sift_down() function. 5. Goto step 2 unless the heap has one element. The build_max_heap() function creates the max heap and takes linear time, O(n). The sift_down() function moves the first element in the heap into its correct index, thus restoring the max heap property. This takes O(log(n)) and is called n times, so takes O(n * log(n)). The complete algorithm therefore equates to O(n + n * log(n)). If you start with a max heap rather than an unsorted array, there will be no difference in the runtime because the build_max_heap() function will still take O(n) time to complete. However, the mere fact you are starting with a max heap means you must have built that heap prior to calling the heap sort algorithm, so you've actually increased the overall runtime by an extra O(n), thus taking O(2n * log(n)) in total.


Difference between Fibonacci heap and binomial heap?

Both Binomial Heap and Fibonacci Heap are types of priority queues, but they have some differences in their structure and performance characteristics. Here's a comparison between the two: Structure: Binomial Heap: Binomial Heap is a collection of Binomial Trees. A Binomial Tree is a specific type of tree with a recursive structure. Each Binomial Tree in a Binomial Heap has a root node and may have children, where each child is also a root of a Binomial Tree of smaller size. Fibonacci Heap: Fibonacci Heap is a collection of trees, similar to Binomial Heap, but with more flexible tree structures. It allows nodes to have any number of children, not just two as in the Binomial Heap. The trees in a Fibonacci Heap are not strictly binomial trees. Operations Complexity: Binomial Heap: Binomial Heap supports the following operations with the given time complexities (n is the number of elements in the heap): Insertion: O(log n) Find minimum: O(log n) Union (merge): O(log n) Decrease key: O(log n) Deletion (extract minimum): O(log n) Fibonacci Heap: Fibonacci Heap generally has better time complexities for most operations (amortized time complexity). The amortized analysis takes into account the combined cost of a sequence of operations. For Fibonacci Heap (n is the number of elements in the heap): Insertion: O(1) Find minimum: O(1) Union (merge): O(1) Decrease key: O(1) Deletion (extract minimum): O(log n) Potential Advantage: Fibonacci Heap: The main advantage of Fibonacci Heap is that it allows constant-time insertion, decrease key, and deletion operations in the amortized sense. This makes it particularly useful in certain algorithms, such as Dijkstra's algorithm for finding the shortest path in a graph, where these operations are frequently used. Space Complexity: Binomial Heap: Binomial Heap usually requires more memory due to the strict structure of Binomial Trees. Fibonacci Heap: Fibonacci Heap can have better space complexity due to its more flexible structure, but this can vary depending on the specific implementation. Real-world Use: Binomial Heap: Binomial Heap is simpler to implement and may be preferred when ease of implementation is a concern. Fibonacci Heap: Fibonacci Heap's advantage in amortized time complexity makes it a better choice in scenarios where frequent insertions, deletions, and decrease key operations are expected. In summary, Binomial Heap and Fibonacci Heap are both priority queue data structures, but Fibonacci Heap offers better amortized time complexity for certain operations. However, Fibonacci Heap can be more complex to implement and may require more memory than Binomial Heap in some cases. The choice between the two depends on the specific use case and the performance requirements of the application.

WHAT IS THE DIFFERENT algorithm of advantage and amp disadvantage?

Different algorithms do different things, so it makes no sense to compare them. For example, the accumulate algorithm is an algorithm which performs the same operation upon every element of a container, whereas a sorting algorithm sorts the elements of a container. Each specific algorithm requires a different set of concepts. An accumulate algorithm requires a data sequence with at least forward iteration and elements which support the operation to be performed, whereas a sorting algorithm generally requires random access iterators and elements that support a given comparison operation (such as the less-than operator).Even if two algorithms have the exact same time and space complexities, it does not follow that both will complete the task in the same time. For instance, the accumulate algorithm is a linear algorithm with a time-complexity of O(n) regardless of which operation is being performed. However, the complexity of the operation itself can greatly affect the actual time taken, even when the operations have exactly the same time-complexity. For instance, if we use the accumulate algorithm in its default form (to sum all the elements in a data sequence), the operation itself has a constant-time complexity of O(1). If we choose another operation, such as scaling each element and summing their products, it will take much longer to complete the algorithm (possibly twice as long) even though the operation itself has the exact same time-complexity, O(1).Consider the time-complexity of adding one value to another:a += bThis has to be a constant-time operation because the actual values of a and b have no effect upon the time taken to produce a result in a. 0 += 0 takes exactly the same number of CPU cycles as 42 += 1000000.Now consider the operation to scale and sum:a += b * 42Here, 42 is the scalar. This also has to be a constant-time operation, but it will take longer to physically perform this operation compared to the previous one because there are more individual operations being performed (roughly twice as many).The only way to compare algorithms is to compare those that achieve exactly the same goal but do so in different ways. Only then does comparing their respective time-complexity make any sense. Even so, time-complexity is merely an indication of performance so two sorting algorithms with the exact same time-complexity could have very different runtime performance (it depends on the number and type of operations being performed upon each iteration of the algorithm). Only real-world performance testing can actually determine which algorithm gives the best performance on average.With sorting algorithms, we often find one algorithm ideally suited to sorting small sequences (such as heap sort) and others ideally suited to larger sets (such as merge sort). Combining the two to create a hybrid algorithm would give us the best of both worlds.


How does Prim's algorithm differ from Kruskal's and Dijkstra's algorithms?

First a vertex is selected arbitrarily. on each iteration we expand the tree by simply attaching to it the nearest vertex not in the tree. the algorithm stops after all yhe graph vertices have been included.. one main criteria is the tree should not be cyclic.

Algorithm to delete?

The only way to delete objects in an object oriented programming language (unless they were created in heap memory) is for the object to go out of scope. If the object is declared in the heap, in c++ you would use delete[] ptr; or delete ptr; where ptr is a pointer to your object.
