| 1 | What are "Coarse Procedures"? | 
| 2 | ----------------------------- | 
| 3 | |
| 4 | A "coarse procedure" is some rough, often handwritten code that solves a subset of a difficult or open-ended task. | 
| 5 | |
| 6 | Example: | 
| 7 | |
| 8 |   static String containsGazelle(String s) {
 | 
| 9 | int dist = levenSubstringIC_limited(s, "gazelle", 2); | 
| 10 | ret dist == 0 ? "yes" : dist == 1 ? "maybe" : "no"; | 
| 11 | } | 
| 12 | |
| 13 | This function detects whether the word "gazelle" or a slight misspelling occurs in a line. | 
| 14 | |
| 15 | For "hello gazelle", the function returns "yes". For "hello gazele", it returns "maybe"... and so on. It uses a variation of the Levenshtein distance algorithm. | 
| 16 | |
| 17 | This is of course not the final function that we actually want, which will be much smarter and adapt to more cases. | 
| 18 | |
| 19 | However, the coarse function is very useful anyway. | 
| 20 | |
| 21 | -We can use it right away | 
| 22 | -It is cheap to run | 
| 23 | -It is predictable, reliable and easy to understand | 
| 24 | -It will do what we want if the input is sufficiently well-formed | 
| 25 | -It gets an intention across | 
| 26 | -It can serve as a basis for an optimization algorithm that generates better code in its place | 
| 27 | ...and more. | 
| 28 | |
| 29 | We can bootstrap an AI system with a bunch of coarse procedures and then proceed to optimize it, be it manually or automatically. |
