I wonder what will be differences between different ranks (I would assume earlier moving toward the center for stronger players), or differences in different years (3-3 earlier and more corners after the AI era?).
What is the widest path (within 19x19, non-handicap games)?
It would also be interesting to see this answer for particular subsets, such as over date ranges (specific years, or pre/post-AlphaGo), for different ranks, etc.
Would it be possible to create a game where the “most commonly played spot” is played for each move? I’m sure there would be some weird stuff or nonsensical moves in the midgame, but still…
It would be the game.
Or even a printout of the top 3 most common moves at each…move.
To make the game, it could be like this: take the most common first move, then reduce the dataset to all games where that move was played, then take the most common second move from that dataset, then reduce the dataset again to only those games where that second move was played, then take the most common third move from that dataset, etc.
Of course it would also be an idea to just see how certain openings (for example, the first 4 moves all being 4-4 point) continue.
I´m very curious how far you could get that way before coming to the point that only a single game is left in the dataset.
Hm, I know a bit of programming but probably not enough to work trough a database of millions of games.
I got a feeling that pros tend to agree on early openings than most (although they tend to evolve over time), and able to follow complicated joseki deep in limited variations, but amateurs would try all kinds of openings, and would diverge fast by not being familiar enough with joseki.
I also wonder what are the number of games each rank played against the number of players in each rank? Would some ranks contribute more than others in proportion?
When writing numbers larger than 999 in figures, there is a convention that you mark off every third column to make it easier to see the size of the number. English speakers usually do this with a comma, thus:
26,935,658
Having information is one thing; communicating it effectively, another.
To my knowledge this only applies to the US, everybody else just uses a (thin) space, if anything at all.
In 2003, the General Conference on Weights and Measures (yes, that’s a thing) decreed thusly: “Numbers may be divided in groups of three in order to facilitate reading; neither dots nor commas are ever inserted in the spaces between groups”, as stated in Resolution 7 of the 9th CGPM, 1948. Now, the US, France and GB are members of that conference, but still they all use different formatting rules for larger numbers.
Brits also use the comma between groups of three in communications aimed at native English speakers. The subject exercising the General Conference in 2003 was whether to use a decimal point to mark off decimals or the decimal comma as used by the French (and others) and the resolution adopted simply reaffirms what the 1948 (9th) convocation had resolved:
Symbol for the decimal marker
Resolution 10
The 22nd General Conference,
considering that
• a principal purpose of the International System of Units (SI) is to enable values of quantities to be expressed in a manner that can be readily understood throughout the world,
• the value of a quantity is normally expressed as a number times a unit,
• often the number in the expression of the value of a quantity contains multiple digits with an integral part and a decimal part,
• in Resolution 7 of the 9th General Conference, 1948, it is stated that “In numbers, the comma (French practice) or the dot (British practice) is used only to separate the integral part of numbers from the decimal part”,
• following a decision of the International Committee made at its 86th meeting (1997), the
International Bureau of Weights and Measures now uses the dot (point on the line) as the decimal marker in all the English language versions of its publications, including the English text of the SI Brochure (the definitive international reference on the SI), with the comma (on the line) remaining the decimal marker in all of its French language publications,
• however, some international bodies use the comma on the line as the decimal marker in their English language documents,
• furthermore, some international bodies, including some international standards organizations,
specify the decimal marker to be the comma on the line in all languages,
• the prescription of the comma on the line as the decimal marker is in many languages in conflict with the customary usage of the point on the line as the decimal marker in those languages,
• in some languages that are native to more than one country, either the point on the line or the comma on the line is used as the decimal marker depending on the country, while in some countries with more than one native language, either the point on the line or comma on the line is used depending on the language, declares that the symbol for the decimal marker shall be either the point on the line or the comma on the line, reaffirms that “Numbers may be divided in groups of three in order to facilitate reading; neither dots nor commas are ever inserted in the spaces between groups”, as stated in Resolution 7 of the 9th CGPM, 1948.
It’s clear that the 1948 resolution was to avoid the anglophone use of commas as separators in large numbers confusing/irritating francophones.
I would agree that for international communications (such as ours) using English as the medium of communication, spaces would be the best choice of separators (and point as decimal separator). Not sure how to make “thin” spaces, otoh.
