CoG 2022 prospects

CoG this year is a small, elite tournament, virtually the same as last year. The entrants, with their win rates in last year’s CoG:

Stardust90.25%Bruce Nielsen
BananaBrain74.69%Johan de Jong
McRave68.17%Christian McCrave
Microwave54.14%Micky Holdorf
PurpleWave52.14%Dan Gant

It’s a fair guess at the likely finishing order. Today’s BASIL ranks and 2021 CoG ranks are the same with one exception, McRave and Microwave are reversed. But PurpleWave has been playing for a long time with one bug that prevents it from doing any upgrades, including basics like dragoon range and zealot speed, and another bug that causes it to construct duplicate buildings. I think it’s a safe guess that the bugs will be fixed for the tournament, and PurpleWave may finish higher.

No terrans. That’s unfortunate.

The carryovers, also with their win rates from last year:

XiaoYi40.10%Benchang Zheng
BetaStar39.29%Ruo-Ze Luo
MetaBot23.08%Anderson Tavares
CUNYBot7.5%Bryan Weber

There’s a note that MetaBot may be dropped due to a tournament stability issue. The decision has not been announced yet.

All updated entrants are likely to outscore all carryovers. XiaoYi is the sole terran, and should not be much of a challenge for current bots. On BASIL, terran krasi0 has just in the last two days retaken its top spot. It would have been good to at least have Hao Pan or Dragon in the tournament.

But there is a silver lining. This is exactly the same participants as last year, assuming that MetaBot is kept. The biggest difference is that CUNYBot is carried over from last year rather than updated. It will be fun to compare relative progress.

Dan on :

PurpleWave's been getting some big changes in the offseason so it's lacked stable versions to upload (and the one I thought was stable is the buggy BASIL version). It's the Jay Scott Law in action: New features weaken; bug fixes strengthen.

The current list of bugs is high impact but shallow and tied to the newly rebuilt systems. So I expect the COG version will be strong.

I'm very excited to have the new changes out; I finally bit the bullet and replaced PurpleWave's two oldest and weakest systems (macro scheduling and building placement). PurpleWave has finally gained the obvious-but-previously-unreliable-due-to-legacy-architecture ability to say "I want one Photon Cannon to defend my third base" and actually get one Photon Cannon reasonably placed in its third base. And it can request both a Gateway and Robotics Facility in either order and get them as soon as possible without a gas shortage delaying both. It's two big monkeys off my back and it feels great.

Jay Scott on :

Good infrastructure is key. If it were possible to get it right the first time, a strong bot would be a lot easier to come by!

MicroDK on :

This year it will only be bug fixes: Bugs from playing on the new maps. And I already fixed two bugs. Wrong calculation of natural base and a crashing bug when no natural base was found which I found during fixing of the first bug. :)
