Dynamic arrays and amortized analysis
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 … WebYufei Tao Dynamic Arrays and Amortized Analysis. 5/12 We will reduce the time of inserting n elements dramatically to O(n).

Sorted by: 2. You should read more precisely the definition of amortized analysis. As we have X operations here, the time complexity of these operations should be divided by the number of operations to find the amortized complexity of the algorithm. Hence, O ( 2X) X is the amortized complexity of the insertion algorithm which …
