Memory-leaks killer... Yes, I am ;)

new heap allocation graphic

This is a the last heap graph of my Chess Robot software: NO MORE LEAKS! We removed also a SIGSEGV on boot and a lot of major and minor bugfixes. Go to the DOWNLOAD section and try the just fresh release (codename Tarkovskij).

This is a graphical rappresentation of the memory allocation of Joshua Chess Robot: it needs a lot of work ;)


Last Release: Codename "Cronemberg".


6 feb 2009 - After a long time (more then a year) we are proud to announce this 0.1.6alpha quite stable snapshot. The code is reindented with lots of cleanup (more useful comments, less unused variables, no more commented code). Also the strategy was rewritten, resulting in a new "personality" not so much aggressive, but no more suicide ;) The new debug system now prints messages in colors and in a crean layout: you can follow the gameplay in the console. All strategy decisions are printed as proteins, just thinking aboud the future genetical decision support environment. Finally, this is the first Joshua Chess Robot released under the GNU GPL v3 License. We hope you like it...
