Analysis of a new skip list variant
Guy Louchard, Helmut Prodinger · Discrete Mathematics & Theoretical Computer Science · 2006
For a skip list variant, introduced by Cho and Sahni, we analyse what is the analogue of horizontal plus vertical search cost in the original skip list model. While the average in Pugh's original version behaves like $Q \log_Q n$, with $Q = \frac{1}{q}$ a parameter, it is here given by $(Q+1) \log_Q n$.
