6 means 1300?
Droidfish strengths

lol! stockfish is a very strong engine unless you decrease its strength.. maybe around 2900+?elo btw 3 is the latest on android

I think I know what he actually means. Droidfish has a power-gauge that goes from 1-100 and he wants to know how to tell what setting on the gauge represents what ELO.
I think it's hard to tell and depends on a lot of additional factors.
Or to put it this way: I don't know it and I think whoever pretends to know is just making a more or less educated guess.

I think it has alot to do with device it's been run on. Obviously be much stronger on a quad core tablet than a $69.99 smart phone. It runs stockfish which is one of the strongest free engines.

ok i get it.. indeed it has adjustable power gauge between 1%-100%.. its very hard to tell what its specific elo and you are right there's so much factor to consider like cp power etc.
a 10% strength of stockfish kick my ...

Maybe looking at the Stockfish-source-code would be the best way to at first find out how changing the gauge affects what the engine does.
If I had to program an engine that doesn't play full strentgh, then I would pick moves that are not the preferred choice but also not lower than a determinable margin.
For example:
Best move is e4, and is evaluated with a +0.24 or something.
Say d4 has +0.21 and Nc3 +0.19 while a4 is -0.28.
If I have a margin of 0.2 for a mediocre difficulty-setting, then d4 and Nc3 are still possible but a4 isn't. If the margin is bigger, say 0.6, then it could also play a4.
So the gauge maybe means something like "allow randomly picking moves that are up to 100-n centipawns worse than the best move".

1 to 100 is the percentage of the UCI Stockfish chess engine options. The Stockfish chess engine internally has a strength level from 0 to 20. Driosfish maps the percentage you give to the range. The default is 20 (strongest level).
For example, 50% on the slider means Stockfish strength level of 10 and 75% is strength level 15.
The increments in strength is non-linear, it quickly converge to the Elo 2700+ for strength levels over 10.
Stockfish with a 0 level doesn't play randomly, it's about 1400 Elo. So the whole Elo range is roughly (1400 to 3000).
I have Droid fish running on a quad-core 1.2 ghz Samsung galaxy tab 4 10.1 inch and nodes per second range from 400 to 600 thousand depending on what stage I am in the game. I set it to 4 threads and set the hash to what has been recommended for 1.5 gigs of ram. My dad has a quad core dell and it gets 3 million nodes per second. His dell is 2 ghz I recall with 4 gigs of ram.

How did you find this thread? amazing, you must've scrolled though a ton of junk to find this.

What is the current strength of droidfish chess engine?? which is using stockfish 9 at this time. If you have a octacore CPU then what is its playing strength??
It plays 1 to 100
I guess 1 is 1200 elo
What about 2?
What about 3 or 4?
Please clear this.I urge to fellow members.
