AIIDE 2022 hardware version - results comparison

The alternate AIIDE 2022 tournament finished. As expected, the top beneficiary was PurpleWave. Well, McRave was the biggest beneficiary in terms of wins, because its frame timeouts fell so much, but it was only enough to pull it up one rank. I thought Steamhammer and Dragon would fall down the ranks, relative to the bots that were no longer timing out, but in fact Steamhammer held its place at #4 and Dragon dropped from #3 to #6. Huh! Steamhammer’s learning does insulate it from its opponents to some extent.

• virtual machine tournament (original)
• hardware tournament (alternate)

Here’s a table comparing the results. The numbers are changes in percentages (not percentage changes). In the vm tournament BananaBrain scored 85.53%, in the hardware tournament it scored 85.03%. The difference is -0.5%.

#	#’	bot	win diff	crash diff	timeout diff
1	1	bananabrain	-0.5%	0	-3.5%
2	2	stardust	-4.86%	-0.8%	-0.2%
5	3	purplewave	+6.27%	+0.04%	-9.88%
4	4	steamhammer	-1.42%	-0.04%	-0.14%
6	5	mcrave	+11.31%	0	-26.55%
3	6	dragon	-9.22%	+3.2%	0
7	7	microwave	-2.62%	+0.18%	-0.9%
8	8	ualbertabot	-1.84%	-0.04%	0
9	9	pylonpuller	+2.86%	0	-0.5%
11	10	cunybot	+2.86%	0	-6.01%
10	11	styx	-2.83%	0	+0.14%

PylonPuller and CUNYBot have identical numbers in the win diff column. It’s a coincidence. Styx somehow had 3 frame timeouts running directly on hardware versus 0 on a vm. It could be bad luck. All other bots had fewer frame timeouts on hardware, unless they already had 0.

Here’s a table comparing totals and averages between the tournaments.

column	vm	hardware
games	12167	12043
game time	12:04	12:56
wall time	4:05	2:42
game timeouts	115	229
crashes	127	117
frame timeouts	1144	90

The hardware tournament ran games much, much faster, and yet had far fewer frame timeouts. And that is even though games ran slightly longer on average in terms of game time, so that more frames were needed.

The hardware tournament had twice as many game timeouts, where the game was adjudicated on points after 60 minutes of game time. I imagine those long games were a disproportionate source of frame timeouts. Longer games are also likely why Dragon had more crashes; it was the only bot to have an important change in crash rate.

AIIDE 2022 - what Microwave learned

Microwave’s history files are completely different from Steamhammer’s, but it’s hard to tell the difference from this summary. The opening names and recognized strategies look alike. They even both recorded 200 games of the 220 or so that were played per opponent.

They’re different in that I can’t speak to Microwave’s exploration strategy.

AIIDE 2022 - what Steamhammer learned

Steamhammer did not record all games, only the last 200. I’ll mention my preparation for different opponents, because it makes a big difference.

Steamhammer’s gas steal achieved nothing significant against any opponent. Maybe next year I’ll disable it.

On BASIL, Steamhammer had been scoring best against BananaBrain with the Phlegethon ling-flood build. If that worked, then I reasoned (without testing) that the similar but more efficient 3HatchLingBust should be better. I gave Steamhammer hints to try both, and I was right. It wins sometimes when BananaBrain incautiously expands too early. Since no opening was good, Steamhammer experimented widely and found a lot of inferior tries.

I expected to score zero against Stardust, or next to it. As it turned out, mutalisk openings held out some hope, and not all wins were due to Stardust crashing (the “wins” timing column gives the median duration of winning games).

Since Dragon was a carryover bot, and Steamhammer was not much changed from last year, my preparation was to drop in last year’s learning file unchanged. The Steamhammer fixes I did make improved defense substantially, though, so Steamhammer in most cases scored better playing the same openings. It discovered AntiFact_Overpool11Hatch on its own, though.

Dragon never allowed a gas steal. And it played the longest games.

For PurpleWave, I gave hints that 3HatchHydraExpo might lose and Over10Hatch might win. On BASIL, PurpleWave had been playing the same opening over and over versus Steamhammer, and I doubted it would do the same in the tournament, so I didn’t have much to go on. Steamhammer made interesting and surprising choices. I would not have guessed that the crazy 7Pool12Hatch would succeed. It’s too bad that the bot discovered it so late in the tournament.

Steamhammer tended to get gas late, a sign that it was either under pressure or else putting on its own pressure instead of teching.

For McRave I gave hints suggesting 5Scout and ZvZ_OverpoolTurtle. 5Scout seriously has scored well against McRave, but not this time—though it does seem to have brought one winning gas steal.

For Microwave I prepared four different ZvZ openings that were successful on BASIL. All were reasonably effective, and ZvZ_Overpool9Gas was excellent. Steamhammer discovered 9PoolHatchSpeed7Drone on its own, very late in the tournament, and won the last 8 games straight with it. Overall, zerglings mostly worked out better than mutalisks, but the median game duration suggests that the win often came after switching to mutas.

For UAlbertaBot I did not provide hints, but configured Steamhammer to always play its best known choice. It’s an extreme turtle build that holds on against all of UAlbertaBot’s rushes and then strikes back. Any experimentation would have lowered the win rate.

No prep needed. The win percentages say that Steamhammer immediately switched away from every opening that lost once.

AIIDE 2022 - what Dragon learned

Dragon records, for each game, only the opening build and the result. It follows up the opening with the same adaptive middlegame, so that games which start out differently tend to shift into looking the same—except for the worker rush opening, which is obviously all-in. Even so, the opening build seems to make a difference.

BananaBrain liked to open with two gates versus Dragon. The vultures are presumably to counter zealots.

But then again, it liked vultures versus dragoon expert Stardust too. It’s interesting that the worker rush was able to score some wins. It looks like a Stardust weakness—BananaBrain defended the worker rush every time.

Steamhammer had a variety of winning builds against Dragon (I’ll post that data tomorrow). I gather that Dragon’s barracks openings are the ones that were able to cope with all the zerg tries about equally well.

Dragon had PurpleWave’s number and did not need to explore alternatives. It looks as though PurpleWave’s numerous timeouts are what made the pairing a blowout rather than a moderate victory, though. Dragon likes long games with lots of units on both sides, which no doubt gave PurpleWave plenty of opportunities to time out. Results so far in the physical hardware version of the tournament are very different.

McRave’s mutalisks may be less skilled against goliaths.

AIIDE 2022 - what BananaBrain learned

BananaBrain added more fields to its game records this year. I had to update my parsing code. I haven’t investigated what the new data is.

Last year, BananaBrain resorted to proxy gates against Stardust, and even that did not help much. This year it preferred the same build that Stardust likes, and apparently it was able to fight it straight up.

BananaBrain was able to tell what Dragon was doing less than half the time. It didn’t seem to matter much, because the answer was usually two gates.

Steamhammer was opposite Dragon in this way: BananaBrain was almost always able to diagnose its opening build, but in the rare when it could not it had some trouble. The impression is that BananaBrain’s reactions were successful but also necessary. Maybe Steamhammer needs to learn how to block its ramp with a drone....

The 10hatch and 9pool are probably misrecognized. It looks like BananaBrain ran over mutalisk specialist McRave with zealots.

AIIDE 2022 - what Stardust learned

I had forgotten that Stardust had learning in last year’s AIIDE, even though I wrote a post about it which explains how it works and wrote code to summarize its learning results.

I’m short of time, so I haven’t checked whether the recording and use of the data is unchanged. But the data format is unchanged, and my code still works. For each of the three specific events, n is the number of games the event occurred and the times are when it occurred in those games.

Every protoss (including random UAlbertaBot) made dark templar sometimes. The median time is near the minimum time, which suggests that the DTs were often rushed. For BananaBrain and PurpleWave, DTs sometimes came quite late. No protoss proxied in Stardust’s base—it would have been a surprise with any of these opponents. Mutalisks were also often rushed. McRave made mutalisks every game. Styx never made a mutalisk, at least not one that Stardust recorded.
