Ieronim,
I have finished benchmarking the routines. I didn't include any from this thread or this one but you are welcome to. I did not penalize any routine for processing the dictionary. Additionally, if there were a number of small variations for a routine, I only included the fastest.

Please note that the winner is just my re-write of Ieronim's code with a few extra bells and whistles. Since the benchmark is extremely long, I have put it in spoiler tags as well as readmore tags:
<Reveal this spoiler or all in this thread>
Update (2006-07-03): These benchmarks do not reflect the realization I made concerning when to test if a path connection has been made that I noted elsewhere in this thread.

Cheers - L~R
