Chess Rating Calculator / News: Recent posts

New version brings a change in GUI. Dialog is wrapped into three tabs: Inputs, Ratings and Results. New button was created in toolbar and in menu to calculate the results. Ratings tab contains three ways how to insert ratings, insert them individually, insert sum of ratings and insert mean rating of opponents.

New version fixes a bug in win32 version. Translations didn't work and the application was started from the console. The win32 now doesn't use the setup, it is a plain zip file that is easy to unzip. In the opponents table, the header was added to help the user input correct values.

Released new version that brings changes from new FIDE rating rules (from 1st of July 2009). Minimal rating was changed from 1600 to 1200. Anand's rule was changed from 350 to 400 points (rating regulations point 8.54). Rating performance table has a new value of 800 for 0 and 100 %. For details take a look at official FIDE page http://www.fide.com/fide/handbook?id=73&view=article

This version brings a rating performance calculation. Language selection is saved upon exit and loaded on start using the Qt's settings mechanism and doesn't depend on system language anymore. Czech and greek translations were also added.

New version of Chess Rating Calculator is released. Visible change is only new application icon, but there is a big change under the hood - we switched from qmake build system to the cmake build system. Now, it is possible to release a debian package, Red Hat's rpm package or windows NSIS setup package from linux environment by issuing one command. We hope, that this will bring some benefits to developers, but also more comfort for users of Chess Rating Calculator. If you are interested in source files, you can download it from our SVN repository.

Chess Rating Calc has switched to cmake build system. It is now possible to create linux and windows executable from linux system using cross-compiler mingw32 issuing just one command. It is also possible to create windows setup package using nsis installer, that is available in linux distributions, we use Debian. You can check it from our SVN repository and release 0.0.7 will use cmake completely.

Version 0.0.4 of free calculator of chess rating is released. Chessratingcalc is still in a pre-alpha state, but is usable for calculation of new rating for players with an old rating. Main new feature is an xml format of saved files, that is better suited for future upgrades than csv format.

I have found a link to my linux version as usable for mac at this softpedia page:

I am proud to present a new version of Chess Rating Calculator - 0.0.2. This version uses coefficient of the grow that can be set to any value, it should be 15 for players who played more than 30 rated games in the past, 25 for players with less rated games and 10 for players who achieved a rating over 2400 in the past. Saving files now remembers the last used file location. However, after adding a customizable coefficient of grow, files saved with version 0.0.1 are unusable in this version.

I have released the first version of Chess Rating Calculator - 0.0.1. This version calculates new ELO rating after setting old rating, number of played games, points won and ratings of opponents. It uses coefficient of the grow with value 15 for all players, what means that it is suitable only for players with old rating under 2400 and with at least 30 games already played. All values may be saved / loaded to a comma separated file.
