NAME

Algorithm::MasterMind::EDA - Solver using an Estimation of Distribution Algorithm

SYNOPSIS

    use Algorithm::MasterMind::EDA;
    my $secret_code = 'EAFC';
    my $population_size = 200;
    my @alphabet = qw( A B C D E F );
    my $solver = new Algorithm::MasterMind::EDA { alphabet => \@alphabet,
                                                length => length( $secret_code ),
                                                  pop_size => $population_size};
  
    #The rest, same as the other solvers

DESCRIPTION

Uses Algorithm::Evolutionary instance of EDAs to solve MM; as there are two different fitness functions you can use; probably fitness_orig works better.

INTERFACE

initialize

Performs bookkeeping, and assigns flags depending on the initialization values

new ( $options )

This function, and all the rest, are directly inherited from base

issue_first()

Yields the first combination

issue_next()

Issues the next combination

feedback()

Obtain the result to the last combination played

guesses()

Total number of guesses

evaluated()

Total number of combinations checked to issue result

number_of_rules ()

Returns the number of rules in the algorithm

rules()

Returns the rules (combinations, blacks, whites played so far) y a reference to array

matches( $string )

Returns a hash with the number of matches, and whether it matches every rule with the number of blacks and whites it obtains with each of them

fitness( $individual )

Computes fitness summing the number of correct black and whites plus the number of rules the combination meets times the length

fitness_orig( $individual )

Fitness proposed in the Applied and Soft Computing paper, difference between the number of blacks/whites obtained by rules against the secret code and by the combination against the combination in the rule.

SEE ALSO

Other solvers: Algorithm::MasterMind::Sequential and Algorithm::MasterMind::Random. Don't work as well, really.
