A tree sort is a sort algorithm that builds a binary search tree from the elements to be sorted, and then traverses the tree so that the elements come out in sorted order. [1] Its typical use is sorting elements online : after each insertion, the set of elements seen so far is available in sorted order.
Lexicographic sorting of a set of string keys can be implemented by building a trie for the given keys and traversing the tree in pre-order fashion; [26] this is also a form of radix sort. [27] Tries are also fundamental data structures for burstsort , which is notable for being the fastest string sorting algorithm as of 2007, [ 28 ...
Radix sort is an algorithm that sorts numbers by processing individual digits. n numbers consisting of k digits each are sorted in O(n · k) time. Radix sort can process digits of each number either starting from the least significant digit (LSD) or starting from the most significant digit (MSD). The LSD algorithm first sorts the list by the ...
These sorts can start sorting their input without having received all of it, and are therefore classified as online algorithms. Pages in category "Online sorts" The following 6 pages are in this category, out of 6 total.
In computer science, a B-tree is a self-balancing tree data structure that maintains sorted data and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree generalizes the binary search tree, allowing for nodes with more than two children. [2]
Initialize an empty splay tree; For each data item in the input order, insert it into the splay tree; Traverse the splay tree in inorder to find the sorted order of the data; Thus, the algorithm may be seen as a form of insertion sort or tree sort, using a splay tree to speed up each insertion.

Then, they maintain the order of the presort during tree construction and hence eliminate the costly step of finding the median at each level of subdivision. Two such algorithms build a balanced k-d tree to sort triangles in order to improve the execution time of ray tracing for three-dimensional computer graphics.
