EGTB Analysis :)

Post by jshriver » Wed Jan 01, 2014 7:53 am

Ok groupies :) I'm planning to write and do a nice egtb analysis toolkit.

BTW I plan to make it open source and also merge the i/o within my "Kraken" project. If you haven't seen it yet do a google search :) still pending but still out there and 100% GPL :)

Anyway long story short...

Looking for "confusing, complex, and curious 3-4-5 and most importantly 6men positions!"

Planning to make a dataset to feed my analyse tool, mostly for checking how quickly, and how accurate the various EGTB are.

-Joshua Shriver
BTW The Kraken project is very alpha right now and not useable if you do go digging :)

You might want to rename your project to avoid confusion with this:

Here is a 5-piece -m71 that I ran into today, at move 60. I would be curious to see what engines or machines could analyze and find the mate from the start of the 5-piece reduction in a timely manner without some sort of TB help.
