    I would like to know what those stupid tracing algorithms mean, when they ask you to 'LABEL' X . I really hate them, most of d1 is easy, i would also like some tips on how to do them, im ok at it when its simple, i do them, but sometimes i end up going in circles and i want to not to do that. Thanks

    Think of LABEL X as a point of reference, an address. So, when you see "GOTO X" in a later line, then return to this point.

    This.

    X then becomes a certain line or point of the algorithm. I dislike tracing algorithms because it's so easy to make a simple little mistake and it never ends and you've gotten it wrong way back!

    Perfect answer. I fully understand it now. Now I am fully prepared for d1.

    Can someone please take the trouble of explaining what 1/2(n-1)! means in the context of calculating the number of hamilton cycles with n vertices. I still dont get it. It's minor things like this that really get on my nerves in D1. I will give a rep again

    I have this exam on tuesday.
    I seriously hate decisions.
    Just seems so pointless from a maths point of view.

    Isn't this the number of hamiltonian cycles in a fully connected graph which is directed? I hope so xD

    D1 is the most boring part of maths ever, but it is outrageously easy
