Arasan 25.1

[Dann Corbit]

A new Arasan day is always a good day.

[F.Huber]

Regarding the second, I don't think it should be necessary to change the name, in a properly functioning GUI.

It seems you don't understand: the GUI (Arena) is properly functioning - the problem is in the Arasan engine!

Here are the corresponding lines from the Arena debug log:
1) the Arasan engine send the following command to the GUI:
81719<1:option name Position learning type check default false

2) the Arena-GUI sends back the following (correct!) string to the Arasan engine:
82188>1:setoption name Position learning value false

3) now the Arasan engine doesn't accept (or understand?) this command and returns following error message to the GUI:
83532<1:info string error: invalid option name "Position learning"

So the problem is definitely in the engine, not in the Arena GUI!

Here is ChessGUI debug info if it helps. Note that I don't use learning:

Yes, but it doesn't stop the engine from playing, and because I usually switch learning off, it doesn't bother me.
For those who want learning to occur, it is an issue though.

[cpeters]

Using

Code: Select all

position_learning

as referenced in arasan.rc (uci-options suggests

Position learning

) gets accepted when started in a terminal (Linux) though.

Concerning the path for the learning-file: it's correctly recognized (Linux)/no error.

greetings

[jdart]

The reported issues with the learning-related options should now be fixed, as of commit b41dec9a722ed5005b802bfc64060401000ad8a4. The fixes will be in the next release.
