General form
I've seen the Rosenbrock function be written in the form $$f(x, y) = (a-x)^2 + b(y-x^2)^2$$. Would it perhaps be better to introduce it in this more general form in this article, then say that usually a = 1 and b = 100? Thanks, A Thousand Doors (talk &#124; contribs) 07:35, 14 May 2014 (UTC)
