Binary Heap Essay

A binary heap is one of the heap structures studied in computer science field at the undergraduate level of learning. There are other various types of heap structures that are about the binary heap, and they mainly include the binomial and Fibonacci heaps. The three heap structures perform the computer operations such as; inserting of keys, getting of the Min(H), deletion of the (H) and lastly on the extraction of (H). These operations are used to give the contrast of these three types of activities on the different perspectives. The other feature used is the union operation since the heaps should be combined in performing the procedures.

Binomial Heap is a combination of several binomial trees in which each of the binomial trees has to follow the property of Min heap. There should be only one Binomial tree at-most of any form of degree. There are two types of the binomial stack, and the first one is the one with 13 nodes while the other one has possession of 12 stacks. The Binomial Heap with control of 13 nodes has a collection of three binomial trees with the orders of 0 to 3 starting from the left side to the right side. The Binomial Heap with possession of 12 nodes has a collection of two Binomial Trees with the orders of 2 and three from the left side to the right side. The Binomial Heap representation is done with n nodes having some Binomial Trees that are equal to the given number of the bits set in the Binary description of an 'n' notation. The operation of the Binomial Heap mainly dwells on the union ().The procedure of the union uses the combination of 2 Binomial Heaps to one full Binary Heap.

The Fibonacci Heap is a collection of the different trees with either the max-heap or the min-heap. Its trees appear to be in an orderly nature. The operation runtimes of the Fibonacci Heaps include; meld:0(1), find-min:0(1) and the decrease-key: Up next!. The Nodes of Fibonacci Heap stores the pointer of its parent, the sibling that is the next, the order of the element and lastly is its part. The Fibonacci Heap has its time complexity reduced of the Decrease-Key possesses much importance in algorithms of the Prim and the Dijkstra. The structure also is slow as it practices the hidden constants that are high. The name Fibonacci heap comes from its primary function of analysis of the running time. Every node in a Fibonacci Heap have 0(log n) degree at its most level and also the size of each subtree rooted on its node has a degree k of less than Fk+2.

The main difference between the Binomial Heap, the Fibonacci Heap and the Binary heap on the insert and delete (min) operations of the structures. The Binomial and Binary heaps have a 0(log n) time of its all activities while the Fibonacci heap has an amortized type of a running time 0(1). Also, it finds a decrease in the fundamental processes and time in the delete-min 0(log n). The delete operations for these three types of heap structures are presented below in a table.

The Binomial and Binary heaps use a link that is single linked and circular in nature while the Fibonacci heaps use a link list that is doubled and circular in nature. There a consideration that every Fibonacci Heap is not a binomial heap while both binomial and binary heaps are a Fibonacci heap. The other difference of the heap structures basing on the Delete-min uses the terminology of the number of trees. The Delete-min of the Fibonacci heaps is calculated without doing the joining of the trees found after deletion. The binary and binomial heaps are done by the combination of trees in the Delete-in operation.

Merging of operation is the process of combining two trees of heap structures by the use of operations of the running time. The Binary heap merges through the combination of the binary max-heap and the binary min-heap. The basic operations of the running time include:

• GetMax: used to return root value at Cost 0(1).
• Insert: use to look into the heap property to be satisfied fully at 0(tree height).
• Priority change: the priority of the node is changed. The Sift Up or Sift Down is done to qualify the property of the heap.
• Remove: there are two steps to help in removal of node A.

Its time bonds depreciate the running time amortized in the time bonds of the Fibonacci heap. Its time bonds include the enqueue which is denoted by 0(1). Also, there is the find-min denoted by 0(1) then meld 0(1). The last two are the decrease-key and extract-min that uses amortization of the Fibonacci heap. Conclusively, the binary, binomial and Fibonacci heaps are all used in the denotation of the computer programs in the performance of the operations.
