I turned the commet #'s into my's in your "declaration" block, added declarations for $line (before the input loop) and $i (in sub check_data) and changed the my $p_e = 0, $p_t = 0; line into two "my" lines. Running the result against a data file containing:

0-0->0-1
0-0->0-2

gave the following output:

begin Lamport's algorithm for input file delme.txt
enter 0-1->0-0 in dependency hashes
enter 0-2->0-0 in dependency hashes

completed delme.txt parsing

I don't know what it means, but the second loop sure is running.

Perl is Huffman encoded by design.
