I suppose that becomes a matter of semantics: What exactly do you mean
by 'fundamental'. If you mean "an integral part of the current
algorithm", then yes. If you mean "it's unthinkable to build a similar
algorithm without the separate state variables" then no. I understand
Fred's comment to take the second interpretation. :)
