Talk:Gift wrapping algorithm

I think this article needs an explanation why it's supposedly O(NK). I don't see why that would be the case. It seems O(N²K) to me. -- Timwi 22:07, 9 Feb 2004 (UTC)

Answer: the outer loop runs K times (since it finds one point on the convex hull during each iteration) while the inner loop (which is not spelled out in the article) runs up to N-1 times. Hence O(K*N).

Where did you get N² from? `'mikka (t) 23:40, 21 July 2006 (UTC)[reply]

The cited Introduction To Algorithms (a must have!) explains the performance. Wouter Lievens 22:59, 21 July 2006 (UTC)[reply]

The citationd doesn't outline higher dimensional extensions, does anyone know about this 129.78.64.106 01:50, 1 February 2007 (UTC)[reply]

The pseudo code is wrong

The algorithm needs to take the smallest angle, not simple the point to the left of all the other points.
