Add links
From Wikipedia, the free encyclopedia

This page provides a list of all articles available at PlanetMath in the following topic:

68-XX Computer science.

This list will be periodically updated. Each entry in the list has three fields:

  1. PM : The first field is the link to the PlanetMath article, along with the article's object ID.
  2. WP : The second field is either a "guessed" link to a correspondingly named Wikipedia article, produced by the script which generated the list, or one or more manually entered links to the corresponding Wikipedia articles on the subject.
  3. Status : The third field is the status field, which explains the current status of the entry. The recommended status entries are:
Status means PM article
N not needed
A adequately covered
C copied
M merged
NC needs copying
NM needs merging
  • Please update the WP and Status fields as appropriate.
  • if the WP field is correct please remove the qualifier "guess".
  • If the corresponding Wikipedia article exists, but the link to it is wrong, please fix the link.
  • If you copy or merge an article from PlanetMath, please update the WP and Status fields for that entry.
  • If you have any comments, for example, thoughts on how the PlanetMath article compares to the corresponding Wikipedia article(s), please place such comments on a new indented line following the entry. Comments of this kind are very valuable.

Don't forget to include the relevant template if you copy over text or feel like an external link is warranted

  • {{planetmath|id=|title=}} for copied over text
  • {{planetmath reference|id=|title=}} for an external link

See the main page for examples and usage criteria.

One can use the web-based program Pmform to convert PlanetMath articles to the Wikipedia format. As a side benefit, this tool will place the PlanetMath template for you.

PM's a bit more mathy, but our descrip is fine as it's not a very mathy subject. CryptoDerk 17:24, Apr 28, 2005 (UTC)

68Q15 Complexity classes (hierarchies, relations among complexity classes, etc.)

You have to jump around to articles on deterministic and non-deterministic machines, etc. but all the major info is there, and more. It's all linked to from this article, as well. CryptoDerk 17:04, Mar 13, 2005 (UTC)
Only merged in bit about space constructible, the rest was fine. CryptoDerk 17:01, Mar 13, 2005 (UTC)

68Q42 Grammars and rewriting systems

68T10 Pattern recognition, speech recognition

Article on PM has some problems, as well as an image that doesn't exist. Theirs goes into a bit more detail, mathematically, but ours explains it better conceptually. I'd say if they get their example fixed, we could merge it in, but until then ours is fine. CryptoDerk 23:50, Feb 4, 2005 (UTC)
