Finally Olithink 5.5.2 has been released. The most interesting new feature is the ability to beat anyone easily in BNK vs K endgame. Example: [Event "Computer Chess Game"] [Site "Olivers-MacBook-2.local"] [Date "2020.07.10"] [Round "-"] [White "OliThink 5.5.2"] [Black "Stockfish 11 64 BMI2"] [Result...

Hi Graham,

thank you for this great tournament.

I have tried to connect to GrahamCCRL.dyndns.org, Port 16001 with the Chess viewer, but I get a "Connection failed. No response from server." each time.
Can you help?

Thank you!

It does not take a lot of code to connect to the Syzygy tablebase files. Proven Elo increase (as opposed to other formats where most experiments show neutral Elo effect).

This is my idea, too. It's the last missing piece that should improve the engine notably with additional little code.

OliThink plays a decent midgame, but still the endgame is not good yet. In 100 games against Glaurung 2.1 (17.0 to 83.0) OliThink has not won a single endgame. More than half of the games are open until endgame. Of the 9 times OliThink won, none of them were endgame wins. Example: [Event "Computer C...

Most notable change is the refactoring of time management and parts of the search function.

It looks like the links for the Java version are out of date. The site says 5.4.11, but the links point to 5.4.6.

Thank you for the hint. I already corrected this before.

I'm thinking shared hash is next. I want to see Olithink mop the floor against the big boys with under 100K of code. No pressure though. :twisted: It's quite difficult to increase strength without expanding code. I omitted a couple of ideas just because they were "too expensive" or "too expansive" :)

OliThink 5.4.13 released.
The frist time I changed something with the very simple Hash(TT)Tables. By this way I doubled the memory usage from 48MByte to 96Mbyte
