AI code library

In order to speed program development and coding I keep a library of code snippets, generic algorithms, etc. including:

finite state machines
string pattern matchers
cellular automata
speech recognition code
least squares fitting
digital control systems
regression analysis
Markov models
semantic networks
various neural network algorithms
various expert system inference engines
fuzzy logic systems
various learning algorithms
optimization algorithms
interpolation algorithms
other statistical algorithms
natural language systems
interfacing and bot code
genetic algorithms
etc., etc.

Some of these I wrote myself, many others I have collected from books, journals, and the web.
