Official Release of OliThink 5.7.5 including a Java-GUI

[OliverBr]

Hello together,
OliThink 5.7.5 has been released and there are some news about it.

- The strength is gaining while code size/complexity is shrinking. 1603 lines of code (45kbyte) with an ELO of almost 2700.
- Executables for Mac64, Linux64 and Win64
- There is an Java Version.
- There is a simple GUI for the Java Version in order to play OliThink "out-of-the-box":



- In order to use this GUI: http://brausch.org/home/chess/OliThinkGUI.jar
(Download, Keep (!) and start with "java -jar OliThinkGUI.jar". Depending on your security settings, you may just double-click the jar-file.)
. It has no pondering and about 1sec/move time, so it won't take much of your computer's resources.
- This Java GUI has less than 200 lines of code and hasn't been changed sind 2009: https://github.com/olithink/olithink5Ja ... Frame.java


PS: A short gauntlet tournament with the C-Version:

Thanks Oliver. A nice comeback!

Thanks Oliver. A nice comeback!

Thank you!

5.7.6 has been released: Queen attacking moves are not being reduced anymore.

The result if kind of mixed, it's winning h2h against 5.7.5, but not again some other engines. Probably because of a little different style of play.

With this release I removed a little bug in http://brausch.org/home/chess/OliThinkGUI.jar. In 5.7.5 the board didn't reset after an illegal move, this has been fixed now.

I got my copy, thanks

I got my copy, thanks

You are welcome!
Still I am finding bugs:

White advantage = 8.98 +/- 4.65
Draw rate (equal opponents) = 41.49 % +/- 0.86

Is ELO +17 enough for a new version?

[towforce]

Could the Java version be hosted in a web page? That would make it super-easy to use - just follow a link!

Don't do a release each time you get a patch in, unless it's a fix for crashes.

Wait at least a month between releases but bring a bundle of patches with elo/features.

As long as the updated code is on github, a release is not necessary

[carldaman]

Well, if new versions all have different playing styles, why not make them available, as he's been doing?

It was hosted on my homepage for many years..
It's a sad story, because security fanatics decided that Java applets were not secure enough and so they vanished... I took OliThink-Applet off my homepage it was nearly impossible to get a browser to run it. I could do it only with Firefox and a lot of configuration.

Perhaps there is a way working with certificates, I just didn't invest anymore because I didn't know if people still wanted it.

PS: The boss of my current job as programmer played the engine when checking the internet for information about me
