NAME

Algorithm::MasterMind::Sequential_Alt - Tests each combination in turn, alternating with the beginning and end of the sequence.

SYNOPSIS

    use Algorithm::MasterMind::Sequential_Alt;

    my $secret_code = 'ADCB';
    my @alphabet = qw( A B C D E F );
    my $solver = new Algorithm::MasterMind::Sequential_Alt { alphabet => \@alphabet,
						       length => length( $secret_code ) };
    

DESCRIPTION

Test combinations in turn, starting by A x length. Should find the solution, but complexity increases with size. Not very efficient, but a bit better than Algorithm::MasterMind::Sequential

INTERFACE

initialize()

Called from base class, mainly

new ( $options )

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

issue_first ()

Issues the first combination, which might be generated in a particular way

issue_next()

Issues the next combination

feedback()

Obtain the result to the last combination played

guesses()

Total number of guesses

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

next_string( $string )

Computes the next string taking into account the limited alphabet, and return the computed string

prev_string( $string )

Computes the previous string taking into account the limited alphabet, and returns it.

prev_letter ( $character )

Returns the previous letter considering the limited alphabet. Needed because magic auto-decrement does not work.
