-**Dear potential co-authors,**
+I am planning to use this codebase, or Joseph A. Hager's, to implement a variation of Copycat that uses *Entropy* instead of *Temperature*, while still preserving the parallel terraced scan in full form.  If the change is viable, I plan to write a paper on that (if anyone is interested in co-authoring, let me know).  For the general idea, please see pages 41 and 42 of the [*Information Sciences*](https://github.com/Alex-Linhares/FARGlexandria/blob/master/Literature/Chess-Capyblanca-2014-Linhares-Information%20Sciences.pdf) paper on [Capyblanca](https://github.com/Alex-Linhares/FARGlexandria).
