- @Bruce: the first proposed patch had the worst case performance of O(infty) due the naive randomize. But I think they got something safe and usable. I didn't find anything very current on the topic... not that used I believe. :)mike3996– mike39962013-02-26 18:22:19 +00:00Commented Feb 26, 2013 at 18:22

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
