If there are no edges in the graph then the proposition is obviously true. This is the base case of induction. Now let G be a digraph with at least 1 edge. By induction, the proposition holds for G − e, where e is any edge in G. Adding this edge back to G − e is where we ...

WebMay 21, 2024 · Now we can complete our proof. We add handshakes one by one onto our handshake graph. Each time the number of people who has had shaken an odd number … WebThe point of induction is to show that this holds for h = k + 1, i.e. x 1 + ⋯ + x n = 2 ( k + 1) when there are k + 1 handshakes. For clarity you might say, for the inductive step, to add a handshake, two people must shake hands with each other. Say person 1 and person 2 are this new handshake. Then we consider the sum.
