Temperature graphs according to KataGo

That's all for tonight. I'll look at the environmental go game on the weekend, as it may need a bit of special treatment, not sure if all the passes will require my Python code to be modified, and I don't want to get into that at this time of night. (Only the first game record is available, not the second?)

OK, I now have graphs for the Spight Adjusted Temperature Method! The raw_temperature line is the same numbers from the first version, and the adjusted_temperature uses Bill's formula. Game_temperature is just the minimum of all the preceding adjusted temperatures.

Example 1: most recent GoGod game, same as post number 1 in this thread.

Very interesting, thanks.

It appears clear that the endgame in this game starts around move 173. At least, the era of extended high temperature fights is over. And it appears that the middle game has started by move 50, maybe earlier. If the nature of the middle game is extended high temperatures, that is.

Unclear what is happening around move 90 and other places with temperature drops. But it may well be that getting the last play before the drop is worth fighting for.

Interesting stuff xela. The environmental go game at http://britgo.org/results/env/index.html would be a good candidate for analysis to see how well the players' thoughts on what the temperature was via when they took the points cards corresponds with KataGo.

Good suggestion, thanks!

SGF at http://britgo.org/files/games/firstenv.sgf -- tried to embed here but EidoGo doesn't like the format, so you'll need to download and view it with different software.

OK, I've kind of fixed the SGF, it had non-standard "result" and "handicap" tags. Now it works in CGoban and q5Go, but still not in EidoGo.

While I was doing this, I realised that I forgot to set the komi in KataGo, so the above analysis assumes komi=7.5. I'll re-run with komi=9.5 to see if it looks any different. Back in an hour or so.

Oh, wait, KataGo thinks white is miles ahead for most of the game, because black is taking more cards. I need to adjust the komi every time there's a pass. Watch this space for updates.

xela · **#27**

OK, try this one instead! (You can see the komi adjustments in the gtp log, if you want to wade through many many lines of text.)

Actually not a huge difference, but before the endgame there's slightly more gap between KataGo's idea of temperature and the top card. We've already noted above that KataGo seems to be overestimating in the opening. The endgame looks pretty good.
