Fibonacci search is not faster than binary search, nor is it primarily useful for sorted arrays. It takes logφ n probes in the worst case, more by a factor of 1.44 than the log2 n probes used by binary search. Its primary use is in searching unimodal arrays, and it is well-described for that use already in Golden section search. I don't see the point in listing it here as a separate article. —David Eppstein (talk) 16:24, 29 May 2008 (UTC)[reply]

David: I am not qualified to comment on accuracy, but consulting reliable sources, and examining the sources cited in the article, should resolve that. If you do not think that the technique warrants a separate article, then you should be proposing that this article be merged to Golden section search. Merely suggesting it in a Talk page post will not make it happen. Fibonacci search already redirects to Golden section search, so merging this article would just create another redirect.

Today's changes, stating more specific circumstances under which Fibonacci search could be an effective replacement for binary search, allay my concerns, so I have removed the disputed tag.
