Re: Progress on Rustic

This is normal. I often see a 10-12 ply extension for QSearch in Rustic as well. It's not a problem. (It's actually what QSearch is intended for: making the position totally quiet.) Question, what are you doing if depth parameter on go is issued? Limit QSearch to that depth or let run QSearch to po...

Re: Progress on Rustic

Confirmed. Rustic is losing on time. When using controls such as move time = 5 seconds, it uses 100% of the time. Overhead protection probably just got lost during refactoring when I was jacking around with the time management a few weeks ago, to prepare Alpha 1. As said, in incremental controls, t...

Re: Progress on Rustic

Thanks for the report. I've created an issue in the repository and I'll look into it for the next release. I'm not going to fix Alpha 1 and do a complete new release for this, because in the beginning, the releases will probably be fairly regular; about once a month or so, maybe 6 weeks. In the fut...

Re: Progress on Rustic

Time control in Rustic alpha seems to be problematic if selecting st=5 in cutechess. (5 seconds per move).
Cutechess-cli is very strict and a few ms passed the allotted time causes a timeout.
Will this get fixed in next release or even in a patch release on alpha?

Re: Alpha-beta fail soft cut-off issue

Meanwhile, I created a version of my program that has the selection in between 3 different algorithms: 1) AB without Beta cut-off 2) AB with Fail-Soft 3) AB with Fail-Hard The rest of the code is the same, same evaluation, same everything... When playing tournaments on different time-controls (bulle...

Re: Alpha-beta fail soft cut-off issue

If you want to detect a score gap (i.e. an 'easy move' situation) you would have to do the searches of the later moves with artificially lowerd alpha. i.e., if your best move scores, say, 30cP, you normally raise alpha to 30 cP, but now you should set it to (say) -70 cP instead). Then the score of ...

Re: Alpha-beta fail soft cut-off issue

I am also not sure why you would want to do this. You can play only one move, so you can extract the best from the list. No reason to sort the others in whatever order. I was thinking of a sorting algorithm that sorts the best x moves, and leaves all the other scores as soon as there is a score gap...
