Newton's method in optimization (can be used to search for where the derivative is zero) Golden-section search (similar to ternary search, useful if evaluating f takes most of the time per iteration) Binary search algorithm (can be used to search for where the derivative changes in sign) Interpolation search; Exponential search; Linear search
A ternary search tree is a type of tree that can have 3 nodes: a low child, an equal child, and a high child. Each node stores a single character and the tree itself is ordered the same way a binary search tree is, with the exception of a possible third node.
The running time of ternary search trees varies significantly with the input. Ternary search trees run best when given several similar strings, especially when those strings share a common prefix. Alternatively, ternary search trees are effective when storing a large number of relatively short strings (such as words in a dictionary). [1]
A ternary computer using fiber optics could use dark as 0 and two orthogonal polarizations of light as +1 and −1. [13] The Josephson junction has been proposed as a balanced ternary memory cell, using circulating superconducting currents, either clockwise, counterclockwise, or off. "The advantages of the proposed memory circuit are capability ...
The above picture is a balanced ternary search tree for the same set of 12 words. The low and high pointers are shown as angled lines, while equal pointers are shown as vertical lines. A search for the word "IS" starts at the root, proceeds down the equal child to the node with value "S", and stops there after two comparisons.
In computer science, a trie (/ ˈ t r aɪ /, / ˈ t r iː /), also known as a digital tree or prefix tree, [1] is a specialized search tree data structure used to store and retrieve strings from a dictionary or set. Unlike a binary search tree, nodes in a trie do not store their associated key.
Sedgewick and Bentley and believe the reason they claim that the ternary tree is "faster than hashing" is because 1. they assume the ternary tree will be stored in RAM and 2. the overhead of calculating a hash can be a fairly heavy (depending on the demands placed on the hash), whereas using bytes of the key itself as hash is trivial.
