Merger proposal

I think it might be good to merge Decision tree model and Decision tree complexity, since there's overlapping information and they can be treated together in one article. --Robin (talk) 04:25, 7 December 2009 (UTC)[reply]

Support. I would say, they have complementary, rather than overlapping information, but the subject is definitely overlapping, so the merge is fairly straightforward cut'and-paste, and I am going ahead, since no objection voiced so far. Also, from the contents of both pages (namely, section titles) I see that the common title would be "DT model," rather than "DT complexity". Twri (talk) 17:29, 30 December 2009 (UTC)[reply]

Certificate complexity (nondeterministic decision tree complexity)

I have added a section on certificate complexity. However, I have not yet added the relationships to the other complexity measures. Feel free to add this! —Preceding unsigned comment added by 129.97.9.222 (talk) 19:46, 19 May 2010 (UTC)[reply]

The "Simple Decision Tree" bound for minimum selection is slack, and consequently a bad example.

Unless I'm majorly misunderstanding something, n - 1 comparisons are clearly needed. I edited to reflect this. I would have also linked to the "Tournament selection" section of Selection algorithm, since that algorithm solves the problem with n - 1 comparisons, but I don't know how to link to a section. A tournament selection page does exist, but unfortunately it talks about a particular application of tournament selection (to genetic algorithms), and I don't want to rock the boat too much.
