Very interesting engine "Sashimi"

[fersbery]

Thought you guys will be interested on this engine: https://github.com/zxqfl/sashimi
Just found it on Github and looks really interesting, even though it is quite weak.
Key features:
- implemented using the Rust programming language
- uses UCT (MCTS) based on the Alpha Zero paper.

Maybe engine testers will be interested on this one since it's very original.

thanks, looks like it could be interesting to play against. anyone have a link to a windows compile?

I'd like to help with compiling, but I am having trouble with this particular project. I am using the latest nightly build of Rust, but when I try to compile I get the error messages below. I think it's some sort of dependency issue, but I am not sure how to solve this. Maybe someone more experienced with Rust can help.

Will try contacting him. If that doesn't work then will try to compile it for Windows and post here.

About the compiling issue, it seems rust nightly version is needed

n.t.

I'd like to help with compiling, but I am having trouble with this particular project. I am using the latest nightly build of Rust,...

[pocopito]

Ok, I didn't' properly read tmokonen's issue with compiling. I used the nighly version of rust and compiled the engine with no problem.

Probably it'd be a good idea opening an issue on the github repo.

[tmokonen]

Would you share your compile with us? I am not sure why I was having trouble with this particular program, as I have compiled other Rust programs before without issues, and I am hesitant to open an issue because it could be an installation issue from my end.

[pocopito]

Sure. I followed the instructions here to get the nightly version (I have no experience at all with rust)
https://www.oreilly.com/library/view/ru ... f418.xhtml

And then just ran the command "cargo build --release --all" from the sashimi folder.

This is the output for what it's worth.

After that I launched the program and tried a couple commands, and it seems to work fine:
