=head1 NAME

Algorithm::Kelly - calculates the fraction of a bankroll to bet using the Kelly formula

=head1 VERSION

version 0.03

=head1 SYNOPSIS

    use Algorithm::Kelly;

    use feature 'say';

    say optimal_f(0.5, 2); # 0.25

=head1 FUNCTIONS

=head2 optimal_f ($probability, $payoff)

Returns the optimal L of bankroll to wager, using the Kelly Criterion, given the C<$probability> and C<$payoff>. Payoff should be the net odds of the wager, so the value of 3-to-1 would be 3. The C sub is exported by default.

=head1 CONVERTING ODDS

Odds are usually presented in one of three styles: decimal, fraction or American. The C sub requires the net decimal odds. These odds are all equal:

    Type      Example    Net Odds

    ----      --------   --------

    Decimal   4.0        3.0

    Fraction  3/1        3.0

    American  +300       3.0

The different odds representations are also explained L.
