Re: New engine releases 2019
Winter 0.5 has been released.
I currently do not have access to a Windows computer, so the binaries are cross compiled from Linux and I am unable to test them on Windows at all.
I switched to Lazy Ignorance SMP as I previously described on the technical section of this forum. On 4 cores this resulted in a minor gain (+10+-7), which tended towards unmeasurable on 14 cores.
Singular Extensions and Counter Move History proved to be very successful ideas in the program. The latter I have not yet seriously tuned. On the other hand neither regular history heuristic nor SFs capture history have proved useful, at least untuned. I have not yet tried continuation histories.
Self play regression at bullet TC currently running:
Winter 0.5 vs Winter 0.4a: 1584 - 605 - 2571 [0.603] 4760
Elo difference: 72.49 +/- 6.65
I expect lower gains than this at longer TC but higher gains on more cores. I think +50 is a realistic conservative estimate for the single core CCRL 40/40 true Elo gain.
The timing of this release is partially due to the upcoming S15 of TCEC which this version (specifically the "new" windows compile) will be submitted to, unless there is something wrong with the binary.

Ancient and Older binaries work here. Speed difference between both may be 3% - only a quick test from cmd with go depth 20 from start position.

FrankWalter 2.3.4 (https://github.com/ljgw/frankwalter/releases/tag/v2.3.4)
- mostly tweaks to time management -
I'm allowing the engine to stop thinking early provided:- It's at the end of a search iteration
- there is no sudden drop in score

What a surprise!
Unfortunately the cfg file hash settings do not seem to work. 119 MB is allocated whatever the setting.

Moustique 0.2
Hello!
I have just uploaded a new version of Moustique on my website.
https://sites.google.com/view/eschecs/moustique
The ZIP file includes Pascal source code and Windows binaries.
It is weak but seems to work well.
It still ignores the parameters of the "go" command and always play at its own rhythm, often instantly, sometimes after one or two seconds.
Best regards.
Roland
