Re: Is cloning a hobby?

I'd like to compare the following routes of making an ultimately closed-source derivative of permissively (non-GNU) licensed origins. 1. Developing it privately until its play becomes distinct enough from the origins' and stronger than them, then opensourcing the resulting v0.0 as a proof of program...

Re: "It must be a clone of some sort..."

It would be interesting to see a differently structured NNUE (with different weights as a result). The fruit of neural architecture optimization must be hanging lower than the search enhancements of 'classical' engines. Given the relative ease of training a small net, it's boring to see it copypaste...

Re: Policy determining quiet early opening preferences of Leela

Wow, I didn't expect SF12 to be so much closer than SF11 to Leela on the first test.

Re: "It must be a clone of some sort..."

If you legally fork someone else's engine rated below 3300 and get it into a TCEC superfinal on your own, which certainly requires a lot of creativity, being an uneven battle vs the large SF and Leela teams, then you can likewise call it almost yours and surely not a clone. The problem is that any s...

On to a julia version.
Awesome, thanks! Just in case, Tord Romstad has changed the license of his Chess.jl to MIT this month :)

Re: Is cloning a hobby?

I assumed that there will eventually be many NN engines that won't be forks of SF nor Leela (nor Scorpio, though you're not mentioned there). That said, you're indeed credited in RubiChess, Igel, and Minic :o Another consideration that I neglected, though, is that TB probing is considered such a sma...

Re: Is cloning a hobby?

Isn't it more interesting to walk through the entire path absolutely from scratch - from complete noob to at least working engine and then hopefully gain a skill to learn from stronger engines? It depends on the personality. One may find some stages of the path boring but necessary for the overall ...

Re: Is cloning a hobby?

As to the definition of 'some very high percentage': to me as a user, 65%+ similarity of a commercial engine to a free one on SIMEX means that I'm better off not buying the former, as its output wouldn't be salient enough to even dedicate resources to running it.

Re: Is cloning a hobby?

My definition is narrow: a clone is a derivative that's been proved to have violated the license of either of its origins, or has at least shown a high level of similarity in tests (currently Ed's SIMEX) with some engine that hasn't been disclosed as its origin. High, as in, a level that's reached b...

Re: Is cloning a hobby?

A move generator can only be two things: - Perfectly accurate - As fast as possible If it's not accurate or it's slow, then it's useless. Same for the board representation: it has to be complete and fast. They have to be complete and obey the chess rules, but they don't have to be fast. Neural engi...
