Steamhammer is submitted
Steamhammer 2.0 is submitted for AIIDE 2018. All I have left is the waiting.
Since yesterday I fixed one bug, a newly introduced bug in the worker manager that could cause a small number of drones to temporarily go idle early in the game, when it matters a lot. I made an attempt to fix a lingering weakness related to cooperating with static defense, but had to roll it back. The fix was a 2-line change, but somehow it caused a hard-to-understand bug, and I can’t accept a risk like that so close to submission time. Also, since an entire day is too long to go without working on the openings, I added a new opening that helps Steamhammer sidestep weaknesses in ZvZ, allowing it to beat more opponents. And I ran all the tests I had time for, looking for new bugs, checking my fixes, and verifying that the new opening functions as intended and earns wins.
It’s hard to understand why, but now I feel tired....
New bot DaQin on SSCAIT matches an AIIDE entrant. It may be the AIIDE entry, or it may be a test version shortly before the entry is made. It looks like a Locutus fork. The .dll is larger than the Locutus .dll by about 24K out of 2.5M—a fair amount of code but no drastic rewrite. The play I’ve seen so far looks similar, lots of dragoons with strong Locutus micro, so without digging deeper I’m not sure what the changes are.
As one of my tests today, I ran a short match Steamhammer 2.0 - DaQin. Steamhammer took several games to find a way to win (not long at all), and after that it won every game, though I didn’t play many and one of the games was excitingly close. I didn’t try the old version Steamhammer 1.4.7, but with Locutus skills I expect that DaQin would have won every game. I don’t think Steamhammer 1.4.x has a way to beat DaQin. It was satisfying to see Steamhammer 2.0 score convincingly, and it helped my confidence.
We’ll see how much Locutus has improved since August!

If you copy other bots or use IP/files/source code/logic/techniques etc from other bots, you must familiarize yourself with their licenses and ensure that you are not infringing their licenses. Copying other bot(s) is allowed, so long as it does not infringe their licenses and so long as you modify their logic or if you use/wrap it without modifying it and add some of your own logic on top of it, similar to how MegaBot used Skynet/Xelnaga/NUSBot in year 2017, or wrapping/modifying Randomhammer/UAlbertaBot/CommandCenter etc. If you do something like this, you must provide the source code and compilation instructions etc of the bots that you use, so that we can compile them. We decided that to foster research it is best to have the next generation of programmers stand on the shoulders of giants, rather than re-invent the wheel. We encourage authors to take code from old years of this competition and improve it. If you copy a bot, please uphold the spirit of competition and ensure you make significant modification or addition before you submit it. We don’t want multiple apparently near-identical copies of the same bot competing! Additionally, please contact the original bot (in case it has been updated at least once during the past year) author and ask them for permission to upload it.
