how to compile ?

[tissatussa]

i tried but i get errors on Xubuntu 20.04 -- what is the correct command to build your binary ? I'm not into Rust ..

It needs to be run with the nightly rust version. Hmm, I thought rust-toolchain.toml should take care of that.

you can try cargo +nightly build

You should also add --release for an optimized build.

[tissatussa]

mmm .. other engine which i compiled also had a 'nightly' problem for me .. now i get this error :

$ cargo +nightly build --release error: no such subcommand: +nightly

i'm not into Rust but i can do things on terminal. how to use nightly's ?

[ianagbip1oti]

Unfortunately I'm not familiar with running rust on xubuntu. For me it automatically installs/uses nightly when I run cargo build because of the rust-toolchain file.

There is some documentation on installing and using nightly in the rust book here https://rust-lang.github.io/rustup/concepts/channels.html

Also, just to make sure they've been seen, I do have release linux binaries in the releases page if you were just looking to run a version of the engine.

[tissatussa]

yes, i use your release now but i could be able to use git clone .. i will need to find out how to use nightly Rust .. i think i will manage .. thanks.

[tissatussa]

at https://bityl.co/8sVL i find info about "Installing Rust nightly" on Linux .. it reads :

With rustup, the tool we installed in Chapter 1, Basics of Rust, it is very easy to install nightly: $ rustup default nightly

Running this command will install the nightly version of the tools (cargo, rustc, and so on). Also, it will switch the corresponding commands to use the nightly version.

If you want to go back to the stable version, issue the following command: $ rustup default stable

but executing this gives me a error / warning :

$ rustup default nightly

Command 'rustup' not found, but can be installed with:

sudo snap install rustup

$ sudo snap install rustup
[sudo] password for tissatussa: 
error: This revision of snap "rustup" was published using classic confinement and thus may perform
       arbitrary system changes outside of the security sandbox that snaps are usually confined to,
       which may put your system at risk.

       If you understand and want to proceed repeat the command including --classic.

normally i install applications only by apt (or Synaptic Package Manager) but nowadays many programs / modules can (or must) be installed using 'snap', which i try to avoid, because it has some drawbacks .. reading the 'error' message makes me hesitate to install rustup and thus nightly ..

what do you say ?

[tissatussa]

i see you update the main code regularly .. i can not build Princhess because i'm unable to build 'nightly' on my Linux (see above) .. so, i download your asset binary, but is that an updated version ? They all are v0.5.0, not v0.5.1 or so ..

[ianagbip1oti]

The binary from releases doesn't keep up with main. There is no more formal process for a release than me just deciding it's time to make one, haha.

If it's something you'd use, I can investigate how I could have "latest dev" binary published somewhere.

[tissatussa]

OK .. and why don't you just create code without 'nightly' stuff ? What is so special about it ? [ I'm not familiar with nightly ]

[ianagbip1oti]

Tbh, because the code base I started from required nightly, haha.

I know it doesn't compile without nightly, I haven't spent time digging into what I'd need to change because of that. But good point on that being another option.

[tissatussa]

yeah, maybe just keep things general and simple ? A final new version should be non-nightly or so anyway, isn't it ? I have no clue when you say "the code base I started" .. do you create a subset of rust functions ? I only know PHP, javascript and Python somewhat ..

[ianagbip1oti]

I mean I didn't start from nothing, I started from https://github.com/zxqfl/sashimi, and the code that's there requires nightly. I'm using this to learn rust as well as chess programming; I haven't spent time seeing what nightly features it uses and for what. I just know it breaks if I remove the nightly requirement.

[tissatussa]

aha .. so you're just using the chess engine code of someone else, and change & add things without breaking it ? I also have that approach while learning, it's OK .. i keep following Princhess.

[tissatussa]

eg. i created new python code to run Sunfish (a simple python chess engine) in a GUI .. i found code to do so, but it lacked something, it was buggy .. better : it didn't work .. however, the author was very detailed and clear and i managed to repair his code and learned a lot, without really understanding the combination of classes, constructions etc. .. python has a great message / warning debug log, since 7 years or so i really like its logic and syntax .. also the community is wide and good. Python is not running fast though compared to a C prog ..

[ianagbip1oti]

Yeah, basically it was more fun to start from something I could already watch play and try to improve it.

[tissatussa]

maybe better discuss things on programming besides this Issue ? -- i'm a chess artist .. and a self-made programmer .. some video edit also .. and lots of experiments in CuteChess with theme games, to improve my play and understanding of our game .. i'm excited about Sashimi ! I gather many open source engines, but not this one .. and it has MCTS !? That's rather unique, not many engines have such .. some even play rather weird, i think .. but MCTS : what is it exactly ? The Sashimi readme is nice though.

[ianagbip1oti]

MCTS is really just an alternative way to explore the game tree. It ends up guided by previous evaluations and some ML stuff.

[ianagbip1oti]

Turns out there wasn't much needed to remove the need for nightly https://github.com/princesslana/princhess/pull/91

[tissatussa]

mmm .. sounds good .. does it mean i might be able to compile your main code into a Linux binary ? I was unable to install nightly (although i'm not a beginner at linux) and i avoid it now, if possible ..

[ianagbip1oti]

I guess give it a try and see what happens

[tissatussa]

we both had ideas but Princhess was too strong for me :-)

[ianagbip1oti]

Awesome. Glad you got her working. Even better that she won :P

[tissatussa]

she played fast, mostly within a second or two .. for a long time i had the advantage but in the endgame she got me ..

https://lichess.org/fonDK68D

[ianagbip1oti]

For the fast, the default hash is small (it's actually 16, not 1), and she doesn't use it very efficiently yet. If you bump it up to 256 or even higher, she has more room to think, so will play a bit slower. On lichess with 2 threads and 1024 hash she usually takes 8-10 seconds per move.

[tissatussa]

i see rating about 1820 in CCRL Blitz list .. but that's 0.3.1 or so .. your Lichess bot shows 2035 for Rapid .. i like her Scandinavian approach with Black, and i tried to convert into my own Blackmar Diemer gambit .. battle of ideas and structures .. do you have any concrete plans to improve her strengh ? And are you a decent programmer to experiment with alternative structures ? I have some ideas ..

BONUS https://www.bitchute.com/video/1FNf33ifFjdl/

[ianagbip1oti]

I don't have anything specific. Just been messing around with ML stuff to see if I can make it's eval of positions or moves better.

[tissatussa]

.. make it's eval of positions or moves better ..

that's a very general answer .. a next question immediately comes up : but how ? I'm thinking of the many parameters used by Rodent, to define a 'personality', which are meant to create many playing styles .. indeed, changing these values gives different results, but it's unclear to me how to distinguish .. do certain FEN positions exist to tune such parameters and improve the overall playing style ? Another example is Odonata, a (Rust!) engine which has an extensive list of changable values -see below-, but maybe you only make use of many (LiChess) games to tune Princhess, as the Sashimi readme states.

to end this Issue, can you elaborate on this ?
