started my fixed nodes leagues

[Uri Blass]

only deterministic engines based on my testing
lowest possible hash.

lowest league mainly 512 nodes per move I call league 1

Velvet promote and it means that next tournament it is going to play only against opponents that search twice more nodes.

PlentyChess and Clover could play illegal move in my testing with 512 nodes and it is the reason I gave them 1024 nodes.
Movei and blunder were weak so they got 3 versions in the first tournament.
Obsidian and BlackMarlin and Igel and Seer got 2 versions because they were also relatively weak with 512 nodes.


Paricipants of league 2:
1)Velvet v7.1.0 512 nodes
2)PlentyChess 1.0.0 2048 nodes
3)Altair 7.0.0 1024 nodes
4)Alexandria-6.0 1024 nodes
5)Seer 2.8.0 2048 nodes
6)Stockfish 16.1 1024 nodes
7)SmarThink 1.98 1024 nodes
8)Obsidian 11.0 2048 nodes
9)Viridithas 12.0.0 1024 nodes
10)Caissa 1.18 1024 nodes

[Uri Blass]

I see that I made a mistake and put alexandria6.0 and not 6.1 in my tournament.
I will repeat league 1 with 6.1 when it should not take a lot of time.

[Uri Blass]

It seems that 6.1 is worse at fixed nodes of 512 nodes so results now are slightly different so here are the results of league 1:

I decided to give the 2 weakest engines in the tournament double promotion in the number of nodes.

Stockfish won league 2 with 1024 nodes

Here are the results of league 2 and you can see that twice doubling the number of nodes was not enough for the weakest engines to get more than 50% so I plan to continue with it and league 3 will also be with 20 entries(stockfish 16.1 1024 nodes promoted to league 3):

[Uri Blass]

PlentyChess promoted to league 5 but I suspect that next promotion belong to Stockfish.
Smarthink and Movei and blunder are going to continue to have 2 entries(2 times faster and 4 times faster but I do not think it is going to help them to get a better place)

[Uri Blass]

Obsidian promoted to league 7.
Stockfish only second place and could not win against 4:1 node disadvantage
Velvet could not avoid last 2 places inspite of 2 updates.

I decided that engines that need more than 1M nodes do not participate in this league so no movei and blunder.

[Uri Blass]

I try to make rating list but I did not combine games of different files
I simply made one rating list for every league.

I got the following for league1.

White advantage = 26.67
Draw rate (equal opponents) = 50.00 %

gap between best and worst is more than 2300 elo.

I will try to have better league in next division simply based on rating.
