Scan 3.0

[Krzysztof Grzelak]

Today I downloaded Scan 3.0 but unfortunately so far the program does not work properly. When running on Windows 64 bit program Scan 3.0 and after running the command cmd - When running in Windows 64 bit Scan 3.0 and after running the command - I have such a picture and no longer play Hub Java.

There is a change in hub.ini; something like:

Code: Select all

engine-command = scan hub

I couldn't do that in the previous version because spaces were not allowed in INI files.

Thank you for your answer Fabien. I have a question about options " ponder = falsethreads ". Does this feature support 1 or more threads. Comparing Scan 2.0 and Scan 3.0 - I understand that Scan 3.0 is stronger than you, compared to Scan 2.0.

Threads (or pondering) haven't changed between Scan 2.0 and 3.0. The example that you give is actually two separate lines. The mix up is due to different text encoding on Windows and Unix. Make sure your file looks like mine (except the values):

Code: Select all

variant = normal
book = true
book-ply = 4
book-margin = 4
ponder = false
threads = 1
tt-size = 24
bb-size = 5

This is what it looks like to me.

Code: Select all

# main

variant = normal
book = true
book-ply = 4
book-margin = 4
ponder = false
threads = 4
tt-size = 24
bb-size = 6

And in the hub folder in the file engine

Code: Select all

variant = normalbook = true
book-ply = 4book-margin  = 4
ponder = falsethreads = 4
tt-size = 24
bb-size = 6

Code: Select all

variant = normalbook = true
book-ply = 4book-margin  = 4
ponder = falsethreads = 4
tt-size = 24
bb-size = 6

So you need to make this file look like the other one, by inserting line endings.

Thank you for the advice Fabien. Excuse me for asking if DXP works while playing with another program on GUI Java.

No DXP support in Hub for now.

Thank you Fabien.

For those interested to see what has changed in the source code, I have updated the GitHub repositories for Scan and Hub to reflect the latest releases (Scan 3.0 and Hub 2.0).

Hi Fabien.

You once wrote that you will share the Scan program (possibly 3.1) with the ability to play on both sides with the function dxp. Can you write when this will happen?

You are changing my words; I said "perhaps".

What do you mean by "the ability to play on both sides with the function dxp"? DXP relies on a network connection between two programs, possibly on different machines. You can already launch two instances of Scan if you want it to play both sides.

[Krzysztof Grzelak]

Thank you for the information Fabien.

Hi Fabien.
Please write if there is a new version of the program Scan - Scan 3.04.

Krzysztof.

Hi Krzysztof,

As a matter of fact, yes. I have implemented additional draughts variants: Frisian and losing (bringing the total number of variants to 5), and am preparing a release. There are also a handful of small changes that would justify using this new version.

However I will need at least a week for a Windows binary (and another for a public release); would that be in time for you?

Fabien.
