Here, T;j = 1 if player i defeated player j in the tournament.
A. Use software of your choice to compute T2, Tª, T³,T16 – this is
most easily accomplished by squaring the matrix successively,
rather than by computing the powers individually.
B. As you successively square the matrix, the columns should begin to
converge to multiples of each other. What's happening is that the
columns are converging to multiples of the dominant eigenvector.
C. According to the relative values of column entries, how should the
participants be ranked?
D. In part C, did you find that any player who won fewer games was
more highly ranked than someone who won more games?
