I believe that's about the time we switched to the new version of the forum software.
All the old posts are still there, but the database doesn't track poster information past that point.
I don't think that's the reason. The "My Content" tab actively stops displaying results past a year ago from the current date. For instance right now it says:
There have been 714 items by Bacterius (Search limited from 28-June 12)
And tomorrow it would say "search limited from 29-June 12", and so on.
That said you can try to dig up your old posts via google. Try "site:gamedev.net "started by [your username]"" or "site:gamedev.net "posted by [your username]"" etc.. (with the inner quotes to get exact hits - also add in some date keywords if you feel extra lucky)
The slowsort algorithm is a perfect illustration of the multiply and surrender paradigm, which is perhaps the single most important paradigm in the development of reluctant algorithms. The basic multiply and surrender strategy consists in replacing the problem at hand by two or more subproblems, each slightly simpler than the original, and continue multiplying subproblems and subsubproblems recursively in this fashion as long as possible. At some point the subproblems will all become so simple that their solution can no longer be postponed, and we will have to surrender. Experience shows that, in most cases, by the time this point is reached the total work will be substantially higher than what could have been wasted by a more direct approach.
