You have the idea right ...
This engine is only supposed to calculate as to begin with what a normal engine
do 'today' where the 'tree' is human edited (some would call it a book), but the
engine will to start with have no book.
This is where the 'human tree' edition is human tree edited...
The other way, seen from endgame view, is that it should be able to calculate
back (some will call it retrograde analysis), you will set methods on some
positions with a primary plan, this would help on the modifying the engines
horizon effect...
With time it will become better.
Yes you are right, to start with the 'tree is empty' and will be time consuming,
but what is not ?
