In this lecture we discuss three methods of amortized analysis: aggregate analysis, the account-ing method, and the potential method. 11.1 Aggregate Analysis In aggregate analysis, one assumes that there is no need to distinguish between the different operations on the data structure. One simply asks, what is the cost of performing a sequence of n
An example of aggregate analysis of dynamic tables is at the end of these notes.
