| # Identify similar programs | |
| Are there patterns in [loda-programs](https://github.com/loda-lang/loda-programs)? | |
| This code generates csv files with a rough estimate of what programs are similar to each other. Only the instructions have been considered. The parameters have not been considered. | |
| The algorithm used for clustering similar programs is [MinHash](https://en.wikipedia.org/wiki/MinHash) or [locality sensitive hashing](https://en.wikipedia.org/wiki/Locality-sensitive_hashing). | |
| # Very similar programs | |
| ```csv | |
| program id;overlap | |
| 7522;25 | |
| 30431;25 | |
| 39949;25 | |
| 45437;25 | |
| 45471;25 | |
| 45473;25 | |
| 61237;25 | |
| 61239;25 | |
| 61241;25 | |
| 61242;25 | |

| 94657;25 | |
| 95995;25 | |
| 100201;25 | |
| ``` | |
| In the above csv file, it seems that these are highly similar: [A007522](https://oeis.org/A007522), [A030431](https://oeis.org/A030431), [A039949](https://oeis.org/A039949). There seems to be a pattern here. | |
| A pattern can serve as a template for finding new programs. | |
| # Less similar programs | |
| LODA programs that are unique, are also interesting. | |
| It may be the beginning of a new useful pattern, that can be applied over and over. | |
| ```csv | |

| ``` | |
| In the above csv file, the `overlap` column is less than 20, and the referred programs are somewhat similar, but with differencies. | |
