Algorithms & data structures

nondeterministic Turing machine

Computer science; Algorithms & data structures

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.

oracle Turing machine

Computer science; Algorithms & data structures

A Turing machine with an extra oracle tape and three extra states q ? , q y , q n . When the machine enters q ? , control goes to state q y if the oracle tape content is in the oracle set; otherwise ...

matrix

Computer science; Algorithms & data structures

A two-dimensional array. By convention, the first index is the row, and the second index is the column.

Post machine

Computer science; Algorithms & data structures

A type of Turing machine that uses a queue instead of an infinite tape to simulate a very simple program formulation. A Turing machine is a hypothetical device that manipulates symbols on a strip of ...

cutting plane

Computer science; Algorithms & data structures

A valid inequality for an integer polyhedron that separates the polyhedron from a given point outside it.

order-preserving Huffman coding

Computer science; Algorithms & data structures

A variable-length character coding based on the frequency of each character. The algorithm is similar to Huffman coding, but the trees are kept in the same order as the characters. Two adjacent trees ...

Shannon-Fano coding

Computer science; Algorithms & data structures

A variable-length coding based on the frequency of occurrence of each character. Divide the characters into two sets with the frequency of each set as close to half as possible, and assign the sets ...
