Graph-tool

Software with no third party reliably published sources that cover it in nontrivial detail and would allow it to pass WP:GNG. There is also no other evidence of notability, and past tags requesting evidence have been removed without improvement. I removed one footnote from the article before taking it to AfD [1] but it does not mention the subject at all and does not even adequately source what it was being used for (the article's claim that a particular programming style provides large speedups). —David Eppstein (talk) 05:40, 21 February 2013 (UTC)[reply]

I have reinserted the link to the scipy performance comparison site. This site is authoritative, it addresses the questiion _directly_ that numerical code implemented in pure python can be orders of magnitude slower than pure C++ (just read the page carefully, including the summary table at the bottom). Furthermore this is _utter_ common sense, and is the reason why projects such as Numpy exists. Here is an excerpt from the Numpy wikipedia article:

Because Python is currently implemented as an interpreter, mathematical algorithms written in it often run slower than compiled equivalents. Numpy seeks to address this problem for numerical algorithms by providing multidimensional arrays and functions and operators that operate efficiently on arrays. Thus any algorithm that can be expressed primarily as operations on arrays and matrices can run almost as quickly as the equivalent C code.[1]

The only citation there is the same one which you had deleted. Please be consistent.

Would you care to elaborate why such similar software as NetworkX and Gephi is considered 'notable', but graph-tool isn't? executive_override (talk) 07:44, 21 February 2013 (UTC)[reply]
