Grobots - Tournaments

There are three tournament series:

Because there is so little activity, none of the tournaments are run on a regular schedule; instead we run them whenever new sides show up. So don't wait for an announcement — send us your sides to enter. Or, since we're often very slow to respond, you could just run the tournament yourself, and send the results to the mailing list.

All of the tournaments use the default rules (100x100 world, ten sides, etc.). The analysis page may be useful for understanding the results.

The giant slayer

(20131208) ISI shows that a side with good tactics can win solidly without exploiting either giants or long range. Its fighters are the first active dodgers by anyone but Warren, and they're much simpler than Warren's (over)fancy implementation. They tend to stay in a group, which helps concentrate force, although it causes significant friendly fire. It also gathers food with force fields, showing that's still competitive. I'm not sure why it's so much better than RK and Active.

Giants and active dodgers

(20120815) It's been two and a half years since the last tournament. Partly as a result of the long gap, we got a record fifteen new entries:

The five active dodgers took the top five places.

Because these sides include three variants of Big Bertha and three of Massive Beast, I also ran a tournament without the duplicates, keeping only RK Bertha and ARG:

Forgotten tournament

(24 Nov 2009, but not posted until 25 Dec - and I thought I was slow about the last one?) David Shellard wrote a lot of aggressive giants, and got five of the top six places. First place goes to The Lunacy, which he describes as an "exploit".

(Devon 20100105) It's not an exploit. The success of the five Massive Beast-based sides is largely because they have heavy long-range weapons, and there are currently no sides that handle that well. While most good sides have fighters that follow the shots back to their source, there are none that dodge well enough to avoid dying before they get there. So until the Massive Beast encounters a large enough force to kill it after suffering losses, it can attack with impunity. Fortunately there is a counter to this. Dodging the shots greatly reduces the damage taken, enabling even a small force to kill a Massive Beast. Warren has demonstrated this with active dodging (in an unreleased variant of Active 6), and it's probably possible to do nearly as well with passive dodging, by simply zigzagging slightly when chasing shots.

At long last

(21 Aug 2008) People have sent me several sides this year, and I've forgotten to run a tournament until now (and I still forgot to include Adaptive 1.3.) Here are the results.

The top five are all well-armed gatherers. I suspect they're ascendant because both their growth rates have been improving (all the top three now have some form of food-sharing), so they exploit territory better than before. The colonial sides are also somewhat lagging in technology - few have food-sharing or dodging, and none know how to hit dodgers. Once they catch up, the performance of the gatherers will probably drop.

I should probably leave the last four sides out of the next tournament, which will be a milestone: finally, Productive and Eventually will be gone.


(18 Dec 2007) Smaller tournament this time - it's just the top 20 from the previous tournament, plus new sides. I kept the old versions of SegE and Revenge Killer to verify that the new ones are better, but only kept the latest version of Weird Men. You could make a case for dropping Productive 5f and Wise Men 2 as well, since they have better derivatives.

Notice the low survival. The top five sides all have a wandering-gatherer component, and fight for territory to gether in. Such sides have very volatile scores - they either win a lot of territory or starve. Competition with the top five means the less well-armed ones scored very badly. Sides which don't need territory (i.e. ones with more solar cells) aren't affected as much.

Shield + Cowards is the opposite extreme - it ignores the world and hides. Its 30% late death rate is remarkable with so many aggressors around. Evidently hiding is more effective when you have better defenses than Productive. But it still has the horrible early-death problem associated with corner-hiding, and it's getting worse as more and more sides do this. Can anyone fix this? Cyclops takes corners reliably by starting with a large (and sophisticated) army, but it must grow very fast to recover. A more cautious approach (like Unproductive, but actively seeking corners) might help, if someone can pull it off.

Even huger

(1 Jan 2007) My new machine runs at 500-1000 fps, so I ran 2007 rounds - more rounds per side than most tournaments have had total. I think I won't include quite as many sides in the next tournament, though - the last eight or so are pretty helpless by modern standards.

Grudge's early score is better than Gunner's. Significantly so. This means provoking enemies is now a bigger problem than ignoring them, at least in the beginning. It doesn't do so well later.

All the gatherers, except Segregated Eaters, have a late death rate more than three times their early death rate. This is partly because their early death rates overstate their early performance, and partly because they're unable to concentrate enough force to win battles in the late game. A wandering gatherer might be improved by deliberately keeping its army in a group.


(20 Nov 2005) This was a bit bigger than usual - 28 sides for 600 rounds (10626346 frames in 41296 s = 257 fps). Error is still pretty big. This table is modified from the output of headless mode. The survival score includes the sterile case, so Not Quite Harmless scores very high.
