Quoting We need help in state machines, combinatorics, parallel and randomized algorithms, heuristics, and quantum computing. I have spent a few hours digging through the site, and have even found one contribution that was somewhat attributed to Abigail. But there were only a few perl implementations to be found. I think this is an area where perl could really show it's true worth.

Update: Athough "quantum computing" is a portion of the site, it doesn't come close to defining the scope of this site or its purpose. Here's a link to the categorized listings, most of which seem to involve sorting string data.
