The National Institute of Standards and Technology (NIST) — known between 1901 and 1988 as the National Bureau of Standards (NBS) — is a measurement standards laboratory and a non-regulatory agency of the United States Department of Commerce. The institute's official mission is to promote U.S. ...
A tree with at most two children for each node. Formal Definition: A binary tree either <ul> <li>is empty (no nodes), or <li>has a root node, a left binary tree, and a right binary tree. </ul>
Industry:Computer science
A trie in which nonbranching subtrees leading to leaf nodes are cut off.
Industry:Computer science
A trie which stores the strings in internal nodes, so there is no need for extra leaf nodes to store the strings.
Industry:Computer science
A Turing machine in which some transitions are random choices among finitely many alternatives.
Industry:Computer science
A Turing machine that is capable of simulating any other Turing machine by encoding the latter.
Industry:Computer science
A Turing machine which has more than one next state for some combinations of contents of the current cell and current state. An input is accepted if any move sequence leads to acceptance.
Industry:Computer science
A Turing machine with an extra oracle tape and three extra states q<sub>?</sub>, q<sub>y</sub>, q<sub>n</sub>. When the machine enters q<sub>?</sub>, control goes to state q<sub>y</sub> if the oracle tape content is in the oracle set; otherwise control goes to state q<sub>n</sub>.
Industry:Computer science
A two-dimensional array. By convention, the first index is the row, and the second index is the column.
