Is Glicko usable for team games? #4

Hi! This is not really an issue, sorry... :-)

Is Glicko usable for team games? I mean, is there a possibility to take into account the strength of each player's team-mates, when calculating new ranking after a tournament?

I did also try Trueskill (https://www.npmjs.org/package/trueskill), which implements Trueskill algorithm from Microsoft, but it seem oriented to one-to-one games, too... :-(

Hi. Glicko does not offer this possibility out of the box, and I don't think there is an easy standard solution to calculate the team rank according to the strength of the players. In my opinion, that algorithm would be tighly linked to the specificity of the game : in the tennis Davis Cup a team with one strong player and two weak players could defeat a team with average players, whereas in the golf Ryder cup the strength of the team follows the average strenght of its players, and in football you'd probably have to take in account the field position of each player...
