Hello everyone,

Many people have asked what the settings of XGRoller were on XG2. Up to that point I had kept that information confidential as it was still a work in progress.

Now that XG2 is almost out, I am ready to disclose that information.

Here are the settings used for the different level of XGRoller in version 2

XGRoller

42 Games using VR with rotation on 21 dice
Truncated after 5 moves using 1-ply
All decisions in 1-ply

XGRoller+

360 games with VR
Truncated after 7 moves using 2-ply
Stop when reaching 0.010 Confidence (minimum 180 games)
First 2 decision in 2-ply
Then 1-ply checker and 2-ply cube

XGRoller++ Checker

360 games with VR
Truncated after 5 moves using 3-ply
First 2 decisions in 3-ply
Then 2-ply checker and 3-ply cube

XGRoller++ Cube

360 games with VR
Truncated after 7 moves using 3-ply
Stop when reaching 0.010 Confidence (minimum 180 games)
First 2 decisions in 3-ply
Then 2-ply checker and 3-ply cube

Note that XGR++ use different settings for cube and checkers. Also XGR+ setting are the same than in version 1. XGRoller was completely redesigned so it was faster and give a in between 3-ply and 4-ply level (on version 1, XGR and 4-ply were quite equivalent in term of speed and strength)
