Advanced options

📝 Rating is a reference value associated with a specific Mortal network and can't be compared across different networks.

1. --player-id <ID>
The ID of the player to review, which is a number within 0-3. It is the number after &tw= in Tenhou's log URL, namely, the player sitting at the East at E1 is 0, and his shimocha (right) will be 1, toimen (across) will be 2, kamicha (left) will be 3. This option has higher priority over the &tw= in --url if specified.
2. See Mortal vs Mortal for comparisons.
3. --temperature <TEMP>
For Mortal engine only. It only affects displayed values and does not change action orders or ratings. Check the FAQ for details.
4. --kyokus <LIST>
Kyokus to review. If LIST is empty, review all kyokus. Example: E1,E4,S3.1, which means to review East-1, East-4, and South-3-1.

The internet is not always stable, and disconnection does occur on occasion. Currently the AI is not capable of reconnection, sorry for the inconvenience.

(Mortal) I find it makes some strange suggestions that I believe are wrong.

Try again but with the more human-like network (mortal3-b24c512-t22121413), which usually produces more moderate or easier-to-understand suggestions than the others.

It may seem at times that this network is stronger, but it's important to remember that statistics are more reliable than subjective feelings. If you have any doubts about the experiment or the statistics, feel free to help review the code.
