Hi Jim,

Can you help us mortals with compiles for the last Integral?

Thank you in advance.

Yes I know. I was simply curious since the updates on this interesting engine are so rare... I ususally build them myself, but Integral is terribly stubborn... they are build errors with both g++ and clang++-20... Otherwise I wouldn't disturb you...

Good morning Jim,
Since Plentychess was released, I've never been able to get good performance from it. My PC only accepts Windows SSE41 or SSE3. However, I explained the problem to Chris, and he managed to compile it in AVX (not AVX2). Now, Plentychess has become one of my best engines, with KNS scores that previously didn't exceed 50, now exceeding 1000. I would appreciate it if you could include AVX (not AVX2) in your compilations. This might solve the problem not only for me but for many other players.

Thank you very much for your attention!

I fully support it! I have already made this request earlier.

Unfortunately, both the author's and your Reckless compilations return the "00000005" error when opening the engine in the console and are completely inoperable.

It was also mentioned above that it doesn't open in Fritz.
I'm writing this only to raise awareness of the issue, and in no way criticize you or the engine creator.
Owners of older hardware are facing increasing problems of this kind; progress is unstoppable.

This is especially frustrating here, as it's currently the second-most powerful game engine, slightly ahead of PlentyChess and Obsidian.

I'm currently using an old CPU (SSE4 only) on Windows 7 Professional. I think the problem comes from windows 7 missing some API extensions.
I found a solution that fixes Reckless and other engines that return the (0xc00000005) error when run.
The tool VexKex adds the needed extensions to Windows.

Warning : it will be detected as a virus by most of the antivirus softwares, but it is safe.
Google yourself "windows 7 API extensions", you will find download pages for VexKex.

Personnally, i used the following one :

Phalanx XXV UCI by Dusan Dobes

Phalanx XXV UCI 64 JA

Update:

Added UCI skill level system for human player.

Key Features
ELO Range: 1000 (beginner) to 2700 (maximum strength), with 18 calibrated profiles in between

Strength Adjustments:
Depth limiting: Weaker levels search shallower (1000 ELO searches to ~200 plies, 2700 searches to ~10000)
Evaluation noise: Random perturbations added to evaluations (-80 to +80 cp for beginners, 0 for strong levels)
Smooth scaling: Linear progression creates realistic strength transitions
-----------------------------------------------------------------

3-fold draw avoidance logic.
When a 3-fold repetition would occur, the engine calculates the current position evaluation
If ahead by 300+ centipawns (configurable), it refuses the draw and continues searching
If not ahead by the threshold, it accepts the draw normally

Configurable Threshold:
Default: 300 centipawns
GUI can adjust via: setoption name RepetitionThreshold value X
Range: 0-2000 centipawns
Value 0 disables the feature entirely

Strategic Benefits:
Engine won't accept draws when clearly winning
Maintains ability to accept draws when behind
Can be tuned per engine strength or opening book preference
Configurable by GUI users
---------------------------------------------------------------

Fixes to mate search.

Good morning Jim,

it's possible to compile Vajolet?
The test version with Neural Network?

Vajolet is a program by Marco Belli, Italy

Hi Jim,

cool, a new Vajolet.
A very strong engine, in the past I had a lot of fun with this engine.

Your logo is nice.
It makes you want to go looking for the Holy Grail.

Vajolet can be the holy grail in computer chess.
After such a long time, a new Vajolet ...
by such a programmer maestro Marco is.
Hope that Marco will have a lot of fun with his development.

Go Vajolet go ...

The day will be good, next week too ... essentially, the next few years.
You know, a new Vajolet ... a secret tip, also for yourself.
Download your own compile ... and after this one ... Vajolet vs. OliThink 5.11.9 NNCe JA-v4

Best and Thanks!
Frank
