Now that is *really unfair. Following an alternative scheme of
writing C(++) programs that are only five lines.

    for(LI n=b.begin(); n != b.end(); ++n) {
        if(_adj_map[node].find(*n) != _adj_map[node].end()) {
            external_cost++;
        }
    }

I almost always write my C code like that. Note that one can save
even more lines and write

    for(LI n=b.begin(); n != b.end(); ++n)
        if(_adj_map[node].find(*n) != _adj_map[node].end())
            external_cost++;

The essential mistake is counting lines. What one should count is the
number of characters.
