Reviewer #3 Report

The paper is a discussion about the use of the twist map for the finite 
Frenkel-Kontorova model. 
The paper does not contain any significant results to be published in any
journal. Therefore, I cannot recommend it for publication in Electronics. 

ANSWER: We have a contradictory meaning.

Reviewer #3 Report

As I wrote earlier, the paper is not rigorously well written. For example, 
Theorem (see line 65-68) is not a Theorem. It seems the authors do not know
what is Theorem is meant.  Moreover, the paper does not contain any new 
results.
