The formula given differs from the cited [https://www.researchgate.net/publication/216300989%20A%20variant%20of%20evolution%20strategies%20for%20vector%20optimization reference[20<nowiki>]</nowiki>]. Function 2 should have the term sin^3(x) or (sin(x))^3 instead of sin(x^3). Please correct it.

* The plot provided is for the constrains as stated. I added the note "(modified)" after the function name, and removed the "dubious" flag. [[User:Pasimi|Pasimi]] ([[User talk:Pasimi|talk]]) 23:32, 9 December 2017 (UTC)
 
<pre>
The quadrant resolved atan2(arg1,arg2) function is ambiguous in terms of the order (e.g. is it FORTRAN-like or Excel)?
Consider resolving by ''t'' = Atan2(arg1,arg2) by explicitly stating the underlying ratios.

== Traceability ==
I recommend that this Wiki page lists only test functions if they are cited with the seminal source, which should be a permanently accessible reference, e.g. journal paper or Zenodo. A good example is H.H. Rosenbrock "An automatic method for finding the greatest or least value of a function" The Computer J. 1960. This will enable double-checking. For example function 'Booth' has no cited source, and is thus eligible to be removed. <!-- Template:Unsigned --><span class="autosigned" style="font-size:85%;">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Peter.schild|Peter.schild]] ([[User talk:Peter.schild#top|talk]] • [[Special:Contributions/Peter.schild|contribs]]) 16:55, 5 September 2022 (UTC)</span> <!--Autosigned by SineBot-->
