The Day–Stout–Warren (DSW) algorithm is a method for efficiently balancing binary search trees – that is, decreasing their height to O(log n) nodes, where n is the total number of nodes. Unlike a self-balancing binary search tree , it does not do this incrementally during each operation, but periodically, so that its cost can be amortized ...

The static optimality problem is the optimization problem of finding the binary search tree that minimizes the expected search time, given the + probabilities. As the number of possible trees on a set of n elements is ( 2 n n ) 1 n + 1 {\displaystyle {2n \choose n}{\frac {1}{n+1}}} , [ 2 ] which is exponential in n , brute-force search is not ...
To index the skip list and find the i'th value, traverse the skip list while counting down the widths of each traversed link. Descend a level whenever the upcoming width would be too large. For example, to find the node in the fifth position (Node 5), traverse a link of width 1 at the top level.
The premise is quite simple: given a sorted list of numbers, binary search eliminates halves of the list in which the number you are looking for cannot lie until it finds the number. However, binary search has lots of subtleties. Surprisingly, when a famous programmer asked his students to implement binary search, 90 percent could not provide a ...
A branch table allows the switch statement to determine with a small, constant number of instructions which branch to execute without having to go through a list of comparisons, while a binary search takes only a logarithmic number of comparisons, measured in the number of cases in the switch statement.
The number and orders of these trees are uniquely determined by the number of nodes : there is one binomial tree for each nonzero bit in the binary representation of the number . For example, the decimal number 13 is 1101 in binary, 2 3 + 2 2 + 2 0 {\displaystyle 2^{3}+2^{2}+2^{0}} , and thus a binomial heap with 13 nodes will consist of three ...
