New engine releases

Sorry to disappoint you but indeed I am a man and the photo is quite up to date !

In french, the "female" version of Vivien is Vivienne. You may also have heart about Vivian (for male) and Viviane (for female).

I learned very useful things today. Thanks Vivien. Good luck with your engine.

Hello,

Please find a new release of Igel engine: 1.2: https://github.com/vshcherbyna/igel/releases/tag/1.2

This release fixes a series bug in Igel, when at random time engine would think that it sees a mate from a given position in transposition table, so it would do a random move, like exchange queen for a pawn. Now that this bug is fixed, I estimate around 30-50 elo increase over previous release (Igel 1.1).

What's new:

- Fixed tt bug that resulted in random blunders
- Fixed NPS bug
- Fixed infinite stop bug
- Implemented POPCNT support

Hi,

I released a new version of WInter yesterday. I want to make a more in depth post later but I am low on time at the moment, so I thought I would mention it here for now.

Winter 0.2 is available on my github https://github.com/rosenthj/Winter with Windows binaries. I will add OSX binaries later. Changes are to search as well as evaluation. Self play between 0.2 and 0.1.1 resulted in +136 +-27 elo after 400 games at 60 +0.6. You can imagine me writing some smart disclaimer about self play results here, but I need my morning coffee first.

Nice, that would put Winter 0.2 at around 2600 elo (CCRL 40/4). If that's correct, I'll include it in next season's CCLS. My plan for next season is to include actively developed engines, no matter if they are weaker than this season's bottom 16. It's a way to help developers show their work

Another nice contribution to a prolific summer.

If I may have a question, which are the files required to run the engine? The zip contains several folders of which not all are needed, I think.

That would be amazing Don't think it is quite 2600 yet, but getting close.

If I may have a question, which are the files required to run the engine? The zip contains several folders of which not all are needed, I think.

Hmm, perhaps I should clean that up =)
Required are 3 files stored in the directories search_params and params. I would just keep those two directories and delete the rest if they bother you. Most GUIs and cutechess-cli allow you to specify engine directories in which the engine expects to find these two directories. I think in the future I will make the engine crash if it can't find the files it needs, but unfortunately I only considered that this is better behavior after someone had an issue immediately after this release.

If you like I could create a compile with a single param folder containing all 3 param files. Its very little work for me.

Taking a quick look at the zip I now realize somehow a .git directory slipped in there, I will see if github allows me to reupload without that directory as there is really no point in it being there. The copying, readme, contributors files as well the src directory are all related to the source and compiling it should someone be interested in that, do you think I should remove that for a binary zip? The data directory has a file containing 6'000 games in a format Winter understands that can be used to benchmark the engine, eg by calling "benchmark x" where x is an integral number that specifies how many milliseconds Winter should spend per test position. The tests directory contains files that can be used for debugging.

One bit of functionality that is actually active in the Winter binary is the ability to train the parameters on a dataset in the same format as the games in the data folder. So far I did not get the impression there would be people interested in this, but if there is demand, I would simplify its usage and add a simple tutorial so people could create their own Winter flavor in version 0.3 =)

Thanks Jonathan. I think removing the github folder would be enough.

Now I have only params and search_params in my Winter folder although they contain 6 files not 3.

To make an engine crash when it does not find the files it needs does not seem an elegant solution to me, at least it should tell the user what is missing.

Is their a Windows binary foe Nemorino 5.01?

Is their a Windows binary foe Nemorino 5.01?

The latest beta is always on the Nemorino main site under (you need to scroll a bit down):

Code: Select all

The current development versions are also available:

    Main Nemorino dev version
    Nemorino dev version for old PC without POPCNT support
