Dynamic arrays and amortized analysis
WebWEEK 2 - Dynamic Arrays and Amortized Analysis. In this module, we discuss Dynamic Arrays: a way of using arrays when it is unknown ahead-of-time how many elements will be needed. Here, we also discuss amortized analysis: a method of determining the amortized cost of an operation over a sequence of operations. WebI learned about amortized analysis and the potential method, I also leaned an example of a binary counter which I think I understand well. In the case of the binary counter I understand the choice of the potential function - we are paying in advance for a transition from one to zero that must be made in the future when a bit changes from zero to one so the …

WebMar 28, 2016 · Amortized Analysis [Dynamic Array] Let x be the size of an empty array. If the array grows full, a new one will be created with a length k > x. The contents of the old array will be copied to the new one, and the new element will be stored as well. Copying an element takes constant time. WebLecture 20: Amortized Analysis. The claim that hash tables have O (1) expected performance for lookup and insert is based on the assumption that the number of elements stored in the table is comparable to the number of buckets. If a hash table has many more elements than buckets, the number of elements stored at each bucket will become large.

WebIn computer science, amortized analysis is a method for analyzing a given algorithm's complexity, or how much of a resource, especially time or memory, it takes to execute. The motivation for amortized analysis is that looking at the worst-case run time can be too pessimistic. ... Dynamic array. Amortized analysis of the push operation for a ...
