3BV of 1 trillion int boards

Postby aradesh » Thu Dec 15, 2016 2:37 pm

So after my expert 3bv run, I decided to run the corresponding int batch.

This time I also kept track of openings, so I have a 2-dimensional table of data here: http://pastebin.com/raw/fXtWPRRR

The highest and lowest 3bv's I found were 7 and 172. I saved all sub 12's and sup 160's. The fewest openings as expected was 1, occurring at a rate of about 1 in 6500.
The most openings I found was 22, which occurred 3 times.
The most common combination of opening and 3bv is 7 openings with a 3bv of 63 occurring 0.735% of the time.

Average 3bv: 64.9217
Standard deviation: 11.6961
Most common 3bv: 63 (3.429% of boards) but only just barely after the
Second most common 3bv: 64 (3.424% of boards)
Most common openings: 7

Ah hah. I worked out how to upload images.

Here are some of the extreme boards.

Interesting. The highest opening count I've found in the wild was 13.

I did extensive int-NF-IOE1 hunting for a while (420 games on MSX, at least 25 on Arbiter).

The highest amount of openings I had an NF-IOE1 on was 12 - which I managed twice, both with a 3bv of 61.

I also have three NF-IOE1 games with a 3bv of 63 and 7 openings.
