+100 elo breakthrough in new rewritten Lco engine ( Ceres)

[corres]

But without commands the Ceres can not work.

What commands are you looking for?
There are none of the setoption UCI commands that Lc0 might use as Ceres only uses the Lc0 backend.
Setup commands are in the json file for things like tablebase directories.
The "go" and other playing commands work.

Which are those other playing commands??
Ceres in the current state can not play like an Leela engine.
Even Ceres can not load as an UCI engine, either.
Did you try at least the "go nodes xyz" commands, for e.g?
I am afraid, not.

Ceres is a UCI engine.
I have done those commands like go and the others and it plays just fine.

No, it does not load like Lc0.
There are no setoption commands.

I have not tried Ceres with a GUI, but it runs just fine with cutechess-cli.

If Ceres work only in cutechess-cli, how can make displayed by somebody the chess board as a chess GUI?
In cutechess-cli engines also need to set its options if you do not want use it in default settings - btw. in your opinions what are the default options for Ceres??
In json file of Ceres there is no any options for an uci engine. Where are they?

While I have not used it in a GUI, based on what others are showing it clearly does work in GUIs.

Update: Ceres runs for me under Arena and Winboard both...

2nd Update: Runs fine under Cutechess GUI also.

This seems to be a list of improvements:

There is no any new announcement there.

Some people are interested in technical details. You are not one of them, but I am not writing for you alone.

I get a 404 error on the boxed ceres.

I can build the LC0 project using the supplied cmd file or the visual studio project.
However, the project is some berserk CMAKE thing that does not allow you to change the project from exe to dll.

Does someone have a solution file that can be modified?

Dan,

Here is a link to the version I compiled on my system. One thing I want to point out is the syntax for the Directory paths much have 2 backslashes in the Ceres.json file.

Code: Select all

{
  "DirLC0Binaries": "C:\\Users\\tedsu\\Desktop\\Ceres",
  "DirLC0Networks": "C:\\Users\\tedsu\\Desktop\\Ceres",
  "DirEPD": ".",
  "DirPGN": ".",
  "DirCeresOutput": ".",
  "DirExternalEngines": ".",
  "DirTablebases": "E:\\SyzygyBases\\DTZ_7;E:\\SyzygyBases\\DTZ_6;E:\\SyzygyBases\\DTZ_345;C:\\SyzygyBases\\WDL_7;E:\\SyzygyBases\\WDL_6;E:\\SyzygyBases\\WDL_345",
  "DefaultNetworkSpecString": "LC0:104130",
  "DefaultDeviceSpecString": "GPU:0",
  "URLLC0Networks": "http://training.lczero.org/networks",
  "LaunchMonitor": false,
  "LogInfo": false,
  "LogWarn": false
}

Here's my Ceres.json file. The network file is a little long, but it works

{
"DirLC0Binaries": "c:\\PhoenixStein",
"DirLC0Networks": "c:\\PhoenixStein",
"DirEPD": ".",
"DirPGN": ".",
"DirCeresOutput": ".",
"DirExternalEngines": ".",
"DirTablebases": "c:\\syzygy",
"DefaultNetworkSpecString": "LC0:20x256SE-jj-9-81000000",
"DefaultDeviceSpecString": "GPU:0",
"URLLC0Networks": "http://training.lczero.org/networks",
"LaunchMonitor": false,
"LogInfo": false,
"LogWarn": false
}

Unfortunately Ceres only support 1-Core dedicated for the GPU at the moment.

I am quite happy with Ceres speed on my 1060GTX card.
17knps on 703810.pb.gz network on Leela vs 25knps on Ceres. Nearly 50% faster speed!

Some observations of Ceres in the current version being tested.

1. Ceres is +100 Elo. False
2. Ceres is 2.3x faster. False.
3. And Lc0 is out searching Ceres by many ply with the same size net.

Current score Lc0 vs Ceres. +2 =28 -0 +23 Elo for Lc0

I will switch Lc0 to the same exact NN after this test.
