This note studies the average-case comparison-complexity of sorting n elements when there is a known distribution on inputs and the goal is to minimize the expected number of comparisons. We generalize Fredman’s algorithm which is a variant of insertion sort and provide a basically tight upper...

It requires 2n elementary operations to apply the map s to a permutation in Sn, so 2nssd(π) is the time complexity of s on the input π. We are interested in the quantity Dn=1n!∑π∈Snssd(π),which is the average depth of the stack-sorting tree on Sn. Note that 2nDn is ...
By contrast, most other algorithms, even those with better average-case complexity, perform their entire sorting process on the set and thus are more complex. However, not only does insertion sort share this advantage, but it also performs better on a list that is substantially sorted (having ...
But where as it might be remotely feasible to hot swap a 100 lb battery, doing so with something that weight 10x requires a significant more degree of automation and complexity. In other words, you need something a whole lot more than a pump that...
Average case analysisAlgorithmsBinary searchThis paper studies the average complexity on the number of comparisons for sorting algorithms. Its information-theoretic lower bound is n lg n 1.4427 n + O ( log n ) . For many efficient algorithms, the first n lg n term is easy to achieve and ...
