Two first Minic wins against Fruit2.1, even one with black pieces

The rest of the 10 short TC games gives 7 wins for Fruit, 2 for Minic and 1 draw ... glad with that ...

What ELO would fruit 2.1 have in CCRL?

Minic 0.28 is out, https://github.com/tryingsomestuff/Mini ... s/tag/0.28 (+80elo since 0.20, current elo should be between 2300 and 2400 at short TC).

Next stage is to add the following evaluation features :
- pawn shield
- blocked pieces
- pieces pair evaluation
- king zone attack
- double pawn
- isolated pawn
(- and maybe candidate passed pawn)

Minic has become a Weini killer ... this is +170elo.

I downloaded your source code and added the minic.json file in the same directory as the .exe. Still, the engine exits immediately.

Let me know how I can get your engine running. I'm interested to run a match between Minic and MadChess since we appear to be at similar points in the development of our engines.

Hi Erik, it needs an xboard param.
e.g.

Code: Select all

minic_0.28_mingw_x64.exe -xboard

[emadsen]

minic_0.28_mingw_x64.exe -xboard

Thanks Guenther!

[xr_a_y]

Here is the final standing against Fruit2.1, this is -270elo, so Fruit2.1 being aroud 2680, this is coherent with Minic being around 2400

[emadsen]

I was curious how our engines compare because we're at similar points of development: we've created bitboard engines with a robust alpha / beta search function but a minimal evaluation function. So I ran a head to head match last night at a time control of 2m+1s. I get very different results than you.

The extra games for MadChess 3.0 are from an earlier gauntlet test I ran against the other engines. In the MadChess vrs Minic match I see no instance of engine crashes or losses on time for either engine.

[xr_a_y]

Very interesting results. I'll check if this is a TC effect. I always test at 40/0:20 and never use standard incremental TC ... so maybe there is something here ...

At least Minic is killing Weini that is 2200 CCRL 40/4

I have a 40/1 head to head against Isa 2.0.64 now and it is quite even for now (only 55 games were played anyway ...)
I'll run something against Myrddin.

How is Minic performing in terms of knps on your hardware, single threaded ?
