String generation
Lua error in package.lua at line 80: module 'strict' not found. In computer science, string generation is the process of creating a set of strings from a collection of rules. This is an opposite process to that of parsing, which recognises a string based on some collection of rules. Generated meaning is Pick at,or pull on
Applications of string generation include test data generation, Captchas and random essay generation.
Generation methods
Methods for generating strings include:
- While a deterministic finite automaton is often used to recognize strings it can easily be changed to generate strings.
Unsolved problems

Note; It is an undecidable problem to decide whether a given string can be generated by a given W-grammar.
