Crafty Play By Elo ( Crafty v25.3)

[MikeB]

The Crafty team is pleased to announce the release of Crafty 25.3 with the addition of a Play of ELO feature - this is strictly a chess players version as there are no other changes to the code. You may also download the Crafty Chess Informant opening books, based on the games published over the last 50 years by Chess Informant. Just include them in the directory where you place the Crafty exe and crafty wil access them automatically.

Will add windows and linux versions as they become available.

Source, macOS exe's and opening books are here:

https://github.com/MichaelB7/Crafty/releases/tag/25.3

To play by ELO insert into the crafty.rc file:

Code: Select all

elo="rating" where rating is any number between 800 and 2600.

A non busy "sleep" for the appropriate time for the time control selected is enabled by default so it will not play instantaneously. Selecting a rating below 1200 enables skill level which will slowly degrade the skill level the more one selects a rating below 1200. A rating between 1200 and 2600 uses Crafty full evaluation function with no deliberate evaluation weakening, it simply reduces the number of nodes searched. Every increase of 100 ELO points will double the number of nodes searched on average. There is also built-randomization factor that varies the number of nodes on any given move to increase variability in play.

Great idea.......Like Brainfish for Crafty.....downloaded new bin files and will check out results!! Thx AR

Awesome. Thank you.

One question: why are there two different ways of setting up parameters in the .craftyrc (according to the demo .craftyrc)?

for example, one time it is

Code: Select all

parameter=value

and then there is also

Code: Select all

parameter value

or is simply both possible?

Both should work , I'm sort of old school and use the "=", old habits die hard.

You should be checking for define _WIN32 to detect a Windows build, not _WIN32__ or __WIN32__. You may want to look at my fork of the Fathom library, which has a bunch of portability fixes:

Trying to compile it with GCC 5.4 ("make windows-gcc" after renaming makefile.win to makefile) I'm getting the following errors:

Any idea what I might have done wrong? Thanks!

I have had problems in the past compiling from some Makefiles.
When having problems, I use the "-Wfatal-errors" flag and try to sort out the errors one at a time.

For macOS , I always use gcc 4.8 without any problems. Not sure if this will solve your problem or not. I'm not any help solving windows issues .
