#possibility_stats(options = {}) ⇒ Object

Runs through every possible outcome of the tournament and calculates each entry’s chance to win as a percentage of the possible outcomes the entry would win if the tournment came out that way. Returns an array of Tournament::Possibility objects for each entry in the pool. These objects respond to :times_champ, :max_score, :min_rank, :entry and :champs methods. The :entry method returns the Tournament::Entry object and the :champs method returns a hash keyed on team name and whose values are the number of times that team could win that would make the entry come in on top. Options avaliable:

:processes => Number of Threads (default: 1) - Set this to the
    number of CPU's on your computer to really peg CPU usage ;)

This method spins up N processes to perform the work and will periodically report progress if passed a block responding to three parameters: 1) percentage of possibilities checked, 2) estimated time remaining in seconds and 3) total possibilities checked so far.
