Development version 11.00.11: elo perfomance

The main feature added is a new value shown when analyzing a game, it is the elo perfomance, a formule created by Michele Tumbarello that calculates the elo of each move and of the game. This formula is designed to do the more accurate results when using MacBrain as engine and a minimum time of 5 second per move.





More news:

  • Captures: added a new option "Material advantage". (Carlo)



Bugs fixed:

  • Replay a game doesn´t show information about captures and comments (thanks to Ed Smith)
  • Linux, main window now can be maximized/minimized (thanks to ACinnamonUserInUK)
  • Some corrections to the tactics of Transsiberian (done by Alfonso Solbes)


Engines:

  • Removed fixed elo of Delphi from 1100 to 2600, maintaining 1000 the only that is working (detected by Serg Iv)
  • New engine: Hannibal 1.7 Authors: Samuel N. Hamilton and Edsel G. Apostol, Home Page: http://sites.google.com/site/edapostol/hannibal
  • Texel updated to 1.07a6
  • McBrain updated to 1.2
  • Removed smarthink, 32 bits version has problems in some pcs.

  1. Hi.
    The new feature of ELO score in analysis is GREAT !!!
    But i have 1460 Elo Fide, and analyzing my games, Lucas Chess gives me a average performance of 2900 ELO !!!
    Thank you

    1. Yes, the Elo performance should be more realistic, if not it would not be useful at all.For example, the overall rating could decrease if a serious mistake is done in the game (a sort of penalty calculation).

    2. The calculation of elo perfomance of the game, now is a simple arithmetic mean.
      Michele Tubarello is the creator of the formula. I have asked him about this.
      Meanwhile, I have tested adding two factors in the mean(only):
      1. no low 1000 limit,
      2. and using the variety of moves in each position as a weight.

      If you want to test:
      https://drive.google.com/file/d/0B0D6J3YCrUouQXJxSGNXc2Y0YkE/view?usp=sharing
      This is a zip file, to uncompress maintaining the folders, to replace 3 files in the installation.

  2. Hi
    In the graph of analysis, what the vertical "red bars" indicate?
    Thank you.

  3. Here on ArchLinux 64 with wine 1.9.22, when playing TourneyElo (vs rose), hamster.exe starts to use a lot of CPU and doesn't stop even when it's my turn. So for now i can't use this version.

    1. Version of Hamster is the problem, it works well with 0.5, if you want to test, change bin file in Engines/Windows/hamster, with the same file in version 10, (or write me an email).

  6. Thank you.
    I will use this space to report a bug:
    i loaded a database with all capablanca games in pgn; when i tried to use the filter option (any of them) to search for instance all the games with alekhine, the system always aplies a e4 opening filter that modifies the result of the filtering, and its impossible to turn off. Please take a look!
    thank you again.

LINUX - First binary version

The first official binary version of Lucas Chess on Linux has just been released. It has only been made possible by the great work done by Laudecir Daniel , choosing and compiling the 67 engines, as well as laying the groundwork so that the binaries can be more widely used and others such as shortcut creation, installation scripts, ...... In addition,  Graham O'Neill  has provided Linux-specific drivers for several digital boards. This version has two limitations : 64-bit Linux OS only. Minimum GNU libc version: 2.26 (ldd --version shows it) Installation has been made as simple as possible: The installer is a .sh file, generated with the  makeself  tool, and can be downloaded from: SourceForge , GitHub The file must be run from a terminal with user permissions only: sh ./LucasChessR123_LINUX.sh Launches a GUI with very basic options: Install: Installs in LucasChessR folder inside the home user folder. Generates a shortcut in Applications > Games Launch the application at the end

R 1.06 Maia

 This update contains a major improvement with the inclusion of Maia. Maia is a neural network chess engine, created with the purpose of making her movements as human as possible. The Maia creation team has prepared 9 versions, from 1100 to 1900 of elo, and thus they have been included in Lucas Chess. You have all the information about Maia at: https://maiachess.com/

Version R

New version of the program. Continuist at user level with the previous one, but with great internal changes. This new version has been mainly tried: Update the code to a current version of the compiler, from python 2.7 to python 3.7 (based in a previous work of Alfonso Solbes). Update the graphic library, from version 4 to 5 of qt, via pyside2. Improve folder organization, with Linux support in mind. Negative consequences: It is incompatible with Windows XP. The data is not compatible with previous versions of Lucas Chess. The weight of the installer has doubled, currently around 120 Mb and the disk installation occupies 338 Mb.
