NAME

Algorithm::SAT::Expression - A class that represent an expression for Algorithm::SAT::Backtracking

SYNOPSIS

use Algorithm::SAT::Expression;
my $exp = Algorithm::SAT::Expression->new;
$exp->or( 'blue',  'green',  '-yellow' );
$exp->or( '-blue', '-green', 'yellow' );
$exp->or( 'pink',  'purple', 'green', 'blue', '-yellow' );
my $model = $exp->solve();
# $model  now is { 'yellow' => 1, 'green' => 1 }

DESCRIPTION

Algorithm::SAT::Expression is a class that helps to build an expression to solve with Algorithm::SAT::Backtracking.

Look also at the test file for an example of usage.

METHODS

and()

Takes the inputs and build an AND expression for it

or()

Takes the inputs and build an OR expression for it

xor()

Takes the inputs and build an XOR expression for it

solve()

Uses Algorithm::SAT::Backtracking to return a model that satisfies the expression.
