A similar but quite easy question :

Q : Find the maximum average subset/sub-array of a given array ? Ans : Maximum Number in Array.

445C - DZY Loves Physics is just a graphical version of this question. But for 1 node,ans is defined to be 0 instead of oo. Hence you pick 2 nodes for which (x[a[i]] + x[b[i]]) / c[i] is maximum
