And the wrong order of the calling positions.
Between the time I typed the place notation into the thing and the time I
collected the numbers and wrote the email talking about it I forgot that the
method I was using wasn't Yorkshire, it was Rutland.
How embarrassing. I really should have looked at the results, and not just the
"If I only had a brain".
For Yorkshire instead of Rutland, I get an even tinier search:
With the breadth first pre-optimi[sz]ation:
1,727 node visitations, in 190 msec, 4.2 per Mcycle
Without the breadth first pre-optimization:
7,259 node visitations, in 200 msec, 16.8 per Mcycle
Sigh. Apologies again for having screwed up by not proof reading.
I come up with 10 total without shunts, but 14 total if I include
shunts, so we're probably getting the same results after all.
