What is the meaning of all derivatives.

I guess that you mean that it has one book book move after 1.d4 g6 2.c4 a6 for
example 3.e4 and after every move of black it has a reply for white

Am I correct?

I guess that the book was based on previous analysis of the program

Am I correct?

How many positions did the program analyze and how much time did your program
analyze in order to create the book?
