6You are in 'detached HEAD' state. You can look around, make experimental

7changes and commit them, and you can discard any commits you make in this

8state without impacting any branches by switching back to a branch.

10If you want to create a new branch to retain commits you create, you may

11do so (now or later) by using -c with the switch command. Example:

13 git switch -c <new-branch-name>

15Or undo this operation with:

17 git switch -

19Turn off this advice by setting config variable advice.detachedHead to false

127[info] GlickmanExampleSpec

128[info] + The implementation of the Glicko2 algorithm should calculate sufficiently similar results as the example in [Mark Glickman's paper](http://www.glicko.net/glicko/glicko2.pdf).

134[info] GW2ExampleSpec

135[info] This example uses "real world" data from the world vs world game mode of Guild Wars 2 to showcase the use of the

136[info] pluggable scoring rules.

138[info] Information how they use Glicko 2 exactly can be found from these sources:

144[info] An updated leaderboard after a rating period should be calculated sufficiently exactly…

145[info] + for rating period 1

146[info] + and rating period 2.

152[info] BattleshipsExampleSpec

153[info] This example is about a group of 5 players competing against each other in the [Battleships game](http://en.wikipedia.org/wiki/Battleship_(game)).

154[info]

155[info] For this example, the rating system is Glicko2(τ = 0.6, defaultVolatility = 0.06)

156[info]

157[info]

158[info]

159[info] + Initially, there are 4 players (Abby, Becky, Chas and Dave) and an empty leaderboard.

160[info]

161[info] During the first rating period, each player plays against every other player. Dave sadly called in sick and thus cannot participate (yet). Abby wins all her games and Becky wins against Chas.

162[info]

163[info] On the resulting leaderboard…

164[info] + Abby's rank is 1 and her rating is greater than Becky's.

165[info] + Becky's rank is 2 and her rating is greater than Chas'.

166[info] + Chas' rank is 3.

167[info] + Only these 3 players are ranked. Dave is not yet on that leaderboard because he has not yet played any games.

168[info]

169[info] In the second rating period, again each player plays against every other player but now Dave has recovered and joins in. Since he's had lots of rest, he wins all of the games. Abby is distracted by her cat and has a losing streak. Becky and Chas' game ends in a draw.

170[info]

171[info] On the resulting leaderboard…

172[info] + There are now 4 ranked players.

173[info] + Abby is now at the lowest rank, she lost the most games.

174[info] + Becky's rank is now 2, she won 1 more game than Chas.

175[info] + Chas' rank is now 3.

176[info] + Dave made an impressive debut, resulting in the highest rank.

177[info] + Dave's deviation (quarter 95% confidence interval, i.e. uncertainty) is the greatest, because he only played 3 games, while the others already played 5.

178[info]

179[info] In the grand finale, a new player, Emma, joins the group. Again, every player plays against every other player. Abby makes a fantastic return as the undisputed queen of Battleships and wins all her games. Becky is on vacation and misses the final rating period completely. Chas and Emma perform equally. Dave loses against Emma.

180[info]

181[info] On the final leaderboard…

182[info] + There are now 5 ranked players.

183[info] + Abby is back at rank 1.

184[info] + Becky rank is still 2, her rating and volatility remain unchanged while her deviation increased because she did not compete during this rating period.

185[info] + Chas ends up at rank 4.

186[info] + Dave starts planning his revenge as he ends up on the last rank.

187[info] + Emma manages to claim rank 3 for herself but her deviation is by far the highest since she only played a few games.
