Great project. Sadly, too weak for my UHO-Top15 Ratinglist, otherwise, I would love to do a testrun. But the EAS-Score is really good for a first release:

Code: Select all

A tournament against some similar strength engines using Stefan Pohl's EAS tool, 
currently the most advanced of its kind, shows Patricia leaps and bounds ahead 
of the pack. Each engine played a total of 3000 games.

Rank  EAS-Score  sacs   shorts  draws  moves  Engine/player 
-------------------------------------------------------------------
   1    185033  22.05%  25.03%  12.30%   65   Patricia  
   2    125386  15.95%  26.71%  19.36%   64   Peacekeeper 1.50  
   3     92720  15.06%  13.10%  15.62%   70   Willow 2.8  
   4     73207  10.61%  14.76%  20.66%   71   Midnight v5  
   5     70947  10.33%  12.76%  19.66%   71   Wahoo v3  
   6     67964  11.17%  15.28%  21.25%   70   Polaris 1.6.1  
   7     56034  04.03%  16.76%  27.24%   68   Akimbo 0.4.1  
-------------------------------------------------------------------

The number of short wins and avg.win moves looks already very good. Some room for improvements (getting a higher EAS-score) are the number of bad draws (goal should be: lower than 10%) and the number of sacrifices (22% is really good, but 30% sacs or more should be the goal, especially, when the engine does not try to get an Elo-strength like Stockfish, Lc0 or Torch)...

The top of the EAS-ratinglist, built out of my old SPCC-ratinglist (where weaker engines were also tested) looks like this:

Code: Select all

                                 bad  avg.win 
Rank  EAS-Score  sacs   shorts  draws  moves  Engine/player 
-------------------------------------------------------------------
   1    282189  35.59%  42.40%  14.89%   64   Velvet 4.1.0 avx2  
   2    262203  37.03%  37.57%  08.50%   68   Komodo 14.1 aggress.  
   3    261076  36.44%  35.46%  12.71%   68   Revenge 1.0 avx2  
   4    257404  31.32%  44.61%  15.44%   64   Velvet 4.0.0 avx2  

But again, Patricia did a great start, mentioning, that it is the very first release... definitly promising.

My Windows defender blocked Velvet 7.0.0 AVX.exe
Virus found
Trojan:Win32/Wacatac.B!ml

Windows Defender has removed some of my engines recently, saying they were Trojans. Last was Clarity 5.1.0 but even Alibaba was deleted (my own compile!). What is annoying is that it does not even issues a warning that it has done so.

So Willow has died? Why?

So Willow has died? Why?

It had become somewhat of a "generic strong engine" which isn't my ideal goal.

Also, Patricia 1.0 had a bug that should now be fixed. The release binaries are updated accordingly.

there's an easy solution:

1. Select Start , then open Settings . Under Privacy & security , select Virus & threat protection.

2. Under Virus & threat protection settings, select Manage settings, and then under Exclusions, select Add or remove exclusions.

3. Select Add an exclusion, and then select from files, folders, file types, or process. A folder exclusion will apply to all subfolders within the folder as well.

Add any/all folders that contain engines...these folders won't be scanned or processed.
