FairRandom is random number generator that outputs more 'fair' numer serquence than true random.

Add this line to your application's Gemfile:

gem 'fair_random'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fair_random

FairRandom::Box.new(N, M) generates numbers that in range 0 to N-1(incusive). There is M numbers in the box and occurence of any number is same, M/N. Each next called, box will remove a element and return it. If box is empty, box contents will regenerate.

(NOTE: M % N should == 0)

# Example
require 'fair_random'

class FairCoinToss
  def initialize
    @rng = FairRandom::Box.new(2, 10)
  end

  # return 0 or 1
  def toss!
    @rng.next
  end
end

You can serialize random state with to_poro/from_poro (with to_json or Marshal etc if needed).

other_instance = FairRandom::Box.from_poro(random.to_poro)
