What is the name of your textbook or reference book?
So I suppose the part you are asking about is the notation [MATH]\sum_{a\in A} f(a)[/MATH]. What this means is that you are summing over all elements of set A. In principle, you would just list all the nodes in that set, and evaluate the summand for each of them.P(u) is a set of nodes.
L(v) is a set of nodes.
I want to understand how to calculate this kind of summation.
Yes, and we could have helped you much quicker if you had stated specifically that it was the parentheses that you didn't understand.First, I would like to thank Dr.Peterson and Subhotosh Khan for their replay and their time. Second, the problem that I had is I couldn't understand the notation that follows ∑, and after I checked out the link above, given by Dr.Peterson, I find that this notation is the binomial coefficients that is given by the formula:
