The (decision version of the) smallest grammar problem is NP-complete. [1] It can be approximated in polynomial time to within a logarithmic approximation ratio ; more precisely, the ratio is O ( log n g ) {\displaystyle O(\log {\tfrac {n}{g}})} where n {\displaystyle n} is the length of the given string and g {\displaystyle g} is the size ...
For readability, this code has been spread across many lines, and blanks and comments have been added. Brainfuck ignores all characters except the eight commands +-<>[],. so no special syntax for comments is needed (as long as the comments do not contain the command characters). The code could just as well have been written as:
No logographic script is composed solely of logograms. All contain graphemes that represent phonetic (sound-based) elements as well. These phonetic elements may be used on their own (to represent, for example, grammatical inflections or foreign words), or may serve as phonetic complements to a logogram (used to specify the sound of a logogram ...
Edit distance finds applications in computational biology and natural language processing, e.g. the correction of spelling mistakes or OCR errors, and approximate string matching, where the objective is to find matches for short strings in many longer texts, in situations where a small number of differences is to be expected.
Order the items from largest to smallest. Initialize an empty bin and call it the "open bin". For each item in order, check if it can fit into the open bin: If it fits, then place the new item into it. Otherwise, close the current bin, open a new bin, and put the current item inside it.
A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. Such program is often the first written by a student of a new programming language, [ 1 ] but such a program can also be used as a sanity check to ensure that the computer software intended to compile or run source ...
Lightweight programming languages are designed to have small memory footprint, are easy to implement (important when porting a language to different computer systems), and/or have minimalist syntax and features. [1] These programming languages have simple syntax and semantics, so one can learn them quickly and easily.
This list gives those most commonly encountered with Latin script. For a far more comprehensive list of symbols and signs, see List of Unicode characters . For other languages and symbol sets (especially in mathematics and science), see below .
