I've decided to delay construction of this new XESTT home page while I refine the work. Most of what is promised in my papers as being on this site may be found on the old XESTT page.
The main thing promised but not delivered yet is conversion of the Curtois and Qu 2014 instances. Actually this has been done but I am still optimizing the converted instances as part of my attempt to solve them.
My apologies for not being as far along as I had hoped.
