Internally is still named 5.0.0:

Hello Sylwy,

Calvin author here. I will release a new .jar and .exe with the corrected version number. Small mistake on my part.

However rest assured the version in question is still 5.0.1, just with an incorrectly reported version number

Thanks,

Dan

[LazySMP]

Hi there, Does any member of CEGT want to test my engine? You can download LazySMP 4.0 from the following link:https://drive.google.com/file/d/1tE4tQf ... SkjhK/view

The CCRL member said he does not want to test my engine because my engine only uses 5MB of hash.

According to Task Manager, your engine is only using 5.7MB hash. Is there a way to set it to use 256MB?

[Moderation] Since this discussion thread is intended just for announcement of new releases, extensive discussions on testing engines are really off-topic here. I therefore split off the discussion that resulted from this posting, to viewtopic.php?t=84505

Thank you! Downloaded. I'll try a short match against Bagatur 5.1c (#2 on my Java list):

The problem is that by default it should be set to false, but it's set to true

You are right. Here is a bug !

The default settings:



The engine window under Arena 3.5.1 (default output):



Settings with pretty=true (probably the true false) in engine configuration window:



Engine output in Arena 3.5.1 in this situation (the normal output):



Unfortunately, when closing the GUI, the setting is lost (and the engine plays weaker).

I stopped the test with Bagatur 5.1c.

Hi Sylwy/Alex,

Good catch, that setting should be false when the engine is being used by a GUI... I think I will implement what I have seen quite a few other engines do, which is to turn it off as soon as the engine receives a 'uci' command (since that is always sent by GUIs, but rarely by humans).

However I am curious that you observed the engine playing weaker after disabling the Pretty option... I'm not sure how that can be, since it always outputs the same 'bestmove' regardless of whether Pretty is on or off. I will run some extra tests to confirm this.

I'll let you know when the new build is ready to download. And sorry for the inconvenience!
