As a former philosophy student, who cared little for mathematics in university, can someone point me in the direction of a resource that would allow me to understand the notation in this article? I understand the problem as described, but unfortunately not the notation.
I can submit random wikipedia articles, too<p><a href="http://en.wikipedia.org/wiki/Upchuck" rel="nofollow">http://en.wikipedia.org/wiki/Upchuck</a>
I've read it several times but I can't understand the problem from the description in this article. Does anyone know of a simpler explanation?
