football_rank

football_rank, a Fortran90 code which ranks college football teams.

A sample file of scores is available from Knuth's Stanford Graph Base. The code reads this file, computes a scoring matrix, and determines a ranking. At the moment, only some of Keener's methods have been implemented.
