Re: Progress on Loki

Good efforts. Good luck with the implementation. It's hard to test this accurately, and it's hard to know what each function would give you with regard to Elo gain. Rustic Alpha 1 is in the CCRL Blitz list at 1675 (I tested it at 1695). I tested Alpha 2 in my own gauntlet, with a result of 1840 (+16...

Re: Thread overhead in C++

Why don't you just check if you exceeded your allotted time, within the search thread? I check for all termination conditions at every 2047 nodes, which works well. A termination condition can be a received stop, quit, depth, moves, nodes reached, max-depth exceeded, or time up. You could have a dif...

Re: PST-only Evaluation for MinimalChess 0.4

I'm finally seeing progress with my tuning attempts. The new PSTs are initialized with material values only (all the tables are filled with 100, 300, 300, 500, 900 etc) and fully tuned they look totally different than PeSTOs. I've made a quick 2000 games test against a previous version with PeSTO t...

Re: DDR5 RAM is coming in 2021

Haha, everytime AMD doubles their core count I hear the champagne corks popping here. ;) Upgrading from my current 4-core i7-6700K to something that has 16 cores (or more) is basically the only thing I'm looking at. It'll probably stay at 32 GB RAM, which I also have now (just because I could two o...

Re: DDR5 RAM is coming in 2021

Is anyone fired up about this? No. It's been some time since I was a teenager. For me a computer is a tool to get stuff done (or play games). At some point, I buy the fastest computer parts I can afford (or wish to spend money on), build the machine, and then I use it for 5-8 years. I replace it wh...

Re: Progress on Loki

Good luck :) Even though many chess engines have been written, it's just cool to have your own. (If you like chess, and are a programmer, that is.) A chess engine is never done, so it's a project that can run for years and years, which you can work on a feature at a time, if you have the time and th...

Re: Progress on Rustic

My old i7-6700K with 32 GB RAM and GTX 1070 is more than fast enough to handle everything, except testing chess engines. 2m+1s is 2m+1s on any computer.... the only thing that helps there is more cores. Or using shorter time controls. I test at 10s fixed, but 50k games, and eight games in parallel ...

Re: New engine releases & news 2021

Aspiration windows didn't work for me, even after trying numerous different window-widening strategies, but I guess it's lazy/hasty implementation is also partly responsible for the missing elo gain... If you need any inspiration for evaluation tuning, I have implemented a rather simple SPSA + Texe...

Re: Progress on Rustic

Take your time. I'd like a chance to catch up. :lol: You already did; you got your bitboards working :) I'm in no hurry; as I've often said, this engine is not in a race to reach a certain Elo rating before a certain time. Because I test literally every single feature I add by running a 1000 games,...
