Today there has been a server update. There have been changes to the way autohosts and the rating system work as well as many minor changes.

Known issues


  • The ladders are missing many players and display unranked players as rank 2147483647. Will be fixed on the next downtime.

Autohosts


Autohost voting has now been streamlined to avoid long vote periods:
  • Directly after each battle there is a 35 second discussion time with no polls.
  • Afterwards, a map majority vote is called. Vote for one of two maps using Yes/No, the map with the most votes wins after 25 seconds. This will be extended to four maps as soon as the UI has been updated.
  • Once the map is selected and if there are more than 6 players a start vote will be called.
  • If the game hasn't been started, normal votes can now be called as usual.

There's also a new option to join small team battles. If there are more than 12 players in the big teams host when a game ends, players will be offered to join small team games. If a player declines he won't be asked again for 10 hours. The team games are created using a modified version of the matchmaker. People waiting in the teams matchmaker will be included if possible.

Ratings


  • Ladder ratings are now chosen such that the rating system is 75% confident that the player has at least that rating.
  • Ratings now have higher variance, meaning they will allow for bigger changes between days.
  • Ratings will change faster the more games are played.
  • Fixed an error in the formula to calculate ratings from team games.
  • Rating uncertainty has been replaced by standard deviation. The +- numbers shown represent one standard deviation.

Minor changes and fixes


  • Fixed some user flags being incorrect.
  • Prevent users from vandalizing empty autohosts by setting custom maps on multiple of them.
  • Only count custom matches for Elo if the teams are even.
  • Spectate afk players on game start.
  • Allow anyone to call !spec to spectate afk players.
  • Only allow allies to vote on in-game kicking.
  • Abort MM battles if a player doesn't load in and ban that player, use !force to circumvent this.
  • Reduce force start time from 180sec to 160sec.
  • Fix autohosts getting deleted on every server restart.
  • Add the logged in player to the end of the ladder if he isn't on it.
  • Add a searchable ladder page with the full ladders.
  • Make sure the Space Lobster rank is unreachable.
  • Prevent an exploit where players could spoof awards and force start games.
  • Fix XP not being given out for some battles.
  • Disallow joining matchmaker if the player is still fighting in another battle and that battle has been going on for less than five minutes.

Follow-up fixes


  • Make ladder inactivity cutoff configurable and don't show the own rank if the player is unranked.
  • Fix some errors with the full, searchable ladders. Introduce a new error with ranks being off by one.
  • Refine the streamlined hosts: No map change after battle ends, no polls after exited battle, nicer map votes.
  • Replace the small teams invitation pop-up by a less obtrusive poll.
  • Refine the chat spam protection to only kick in after multiple spammed messages.

I would give you more than one upvote if I could for these changes!

I was wondering when the small team invite from lobsterpots would be implemented.

Quick question for Linux users: After this update, do you still need to delete the files in games/ to run Zero-K.exe without hanging?

Very good! I really like the change to standard deviation, how ladder rating is calculated, map votes, that uneven custom games are excluded and afkers specced.

The following two things make me curious, though:

Ratings now have higher variance, meaning they will allow for bigger changes between days.
How much higher? What is the new rating variability w²? Previously, it was already 35/day where only 14/day is used in the WHR paper. If it is this ω² shown at the rating charts, I'm wondering in which units it is. Looking at current ZK ratings, it seems like variance has increased by a factor of about 2000. I see not a sinlge player, not even RUrankFirepluk, with a standard deviation of less than 100. This means that all variances are now bigger than 10000.

Could you explain in more detail what this means?

Never had to, and still no need of doing it.

The ZeroK-Linux-Mono hang-up still occurs on my end, including after a full system upgrade.

There has been a follow-up update to fix the biggest issues. Please report any bugs you encounter.

DErankBrackman I'll make another post detailing the changes to WHR.

newest lobby stuff is a desease for teamgames,
after each game you first get spammed by matchmaker (why you think im in clusterfuck teamgames rooms, cuz i NOT wanna be annoyed by matchmaker shit)... is there any option to turn that annoying off?
then you get 4 shitmaps to vote for
then you cant start a poll for another map for period of time... why am i in this room, not to chat!
